Unable to build Info pages using "make info"

Hello,

I have updated to the latest master and trying to build git plus its Info manuals.

I am on RHEL 6.8. It does not have docbook2x-texi, but I was able to install docbook2texi from https://sourceforge.net/p/docbook2x.

The whole git build goes fine except when it reaches the "make info" step. I get these errors:

MAKEINFO git.info user-manual.texi:15: warning: empty menu entry name in `* : idp4751360.' user-manual.texi:141: warning: @unnumbered missing argument user-manual.texi:3204: warning: @ref cross-reference name should not contain `:' DB2TEXI gitman.texi MAKEINFO gitman.info novalidate not a possible customization in Texinfo::Parser::parser gitman.texi:1610: @ref reference to nonexistent node `ATTRIBUTES' gitman.texi:3165: @pxref reference to nonexistent node `CO1-1' gitman.texi:3181: @pxref reference to nonexistent node `CO2-1' gitman.texi:3186: @pxref reference to nonexistent node `CO2-2' gitman.texi:5070: @pxref reference to nonexistent node `CO1-1' gitman.texi:5075: @pxref reference to nonexistent node `CO1-2' gitman.texi:5079: @pxref reference to nonexistent node `CO1-3' gitman.texi:5129: @pxref reference to nonexistent node `CO2-1' gitman.texi:5132: @pxref reference to nonexistent node `CO2-2' gitman.texi:5135: @pxref reference to nonexistent node `CO2-3' gitman.texi:5475: @pxref reference to nonexistent node `CO1-1' gitman.texi:5481: @pxref reference to nonexistent node `CO1-2' gitman.texi:5484: @pxref reference to nonexistent node `CO1-3' gitman.texi:5489: @pxref reference to nonexistent node `CO1-4' gitman.texi:7466: @ref reference to nonexistent node `EXAMPLES' gitman.texi:7476: @ref reference to nonexistent node `FILES' gitman.texi:7559: @ref reference to nonexistent node `FILES' gitman.texi:7569: @ref reference to nonexistent node `FILES' gitman.texi:7578: @ref reference to nonexistent node `FILES' gitman.texi:7785: @ref reference to nonexistent node `FILES' gitman.texi:12524: @ref reference to nonexistent node `FILES' gitman.texi:12630: @pxref reference to nonexistent node `INPUT/OUTPUT FORMAT' gitman.texi:12938: @pxref reference to nonexistent node `ISSUES' gitman.texi:13353: @pxref reference to nonexistent node `DATABASE BACKEND' gitman.texi:13488: @pxref reference to nonexistent node `configaccessmethod' gitman.texi:19956: @pxref reference to nonexistent node `CO1-1' gitman.texi:19959: @pxref reference to nonexistent node `CO1-2' gitman.texi:19963: @pxref reference to nonexistent node `CO1-3' gitman.texi:19978: @pxref reference to nonexistent node `CO2-1' gitman.texi:19982: @pxref reference to nonexistent node `CO2-2' gitman.texi:19987: @pxref reference to nonexistent node `CO2-3' gitman.texi:20001: @pxref reference to nonexistent node `CO3-1' gitman.texi:20004: @pxref reference to nonexistent node `CO3-2' gitman.texi:20007: @pxref reference to nonexistent node `CO3-3' gitman.texi:20022: @pxref reference to nonexistent node `CO4-1' gitman.texi:20026: @pxref reference to nonexistent node `CO4-2' gitman.texi:20030: @pxref reference to nonexistent node `CO4-3' gitman.texi:20043: @pxref reference to nonexistent node `CO5-1' gitman.texi:20047: @pxref reference to nonexistent node `CO5-2' gitman.texi:22570: @pxref reference to nonexistent node `[CRTB]' gitman.texi:22935: @pxref reference to nonexistent node `[CRTB]' gitman.texi:23278: @ref reference to nonexistent node `Remap to ancestor' gitman.texi:23394: @ref reference to nonexistent node `Remap to ancestor' gitman.texi:27608: @pxref reference to nonexistent node `CO1-1' gitman.texi:27611: @pxref reference to nonexistent node `CO1-2' gitman.texi:27614: @pxref reference to nonexistent node `CO1-3' gitman.texi:37177: @pxref reference to nonexistent node `[OPTIONS]' gitman.texi:41101: @pxref reference to nonexistent node `CO1-1' gitman.texi:41107: @pxref reference to nonexistent node `CO1-2' gitman.texi:41110: @pxref reference to nonexistent node `CO1-3' gitman.texi:41117: @pxref reference to nonexistent node `CO1-4' gitman.texi:41133: @pxref reference to nonexistent node `CO2-1' gitman.texi:41138: @pxref reference to nonexistent node `CO2-2' gitman.texi:41141: @pxref reference to nonexistent node `CO2-3' gitman.texi:41159: @pxref reference to nonexistent node `CO3-1' gitman.texi:41165: @pxref reference to nonexistent node `CO3-2'

I have searched online in general and also in the archive of this mailing list, but have't seen this issue before. So something in my build process is not right.

Can someone point out a known issue on old RHEL 6.8 systems that can cause this, and also the workaroud?

Here's my build script: https://ptpb.pw/Rcco/bash .

Thanks! And please CC me on all the replies.
