Well, "make" won't break (I think), but "make test" very well might.

Well, so far all OpenSource packages ported to HP NonStop (at least the ones on ituglib.connect-community.org) use prefix=/usr/local and there is no intention to change that.
A few (bash, vim, coreutils, tar, gzip, bzip2) get delivered with the system meanwhile (rather than having to be downloaded and installed by the customer) and live in /usr/corutiles. Still more are needed (e.g. diff , make).
The next lines in my patch cater for that, it is missing though an automatic switch.
Such a switch would be possible, using 'uname -r' and 'uname -v', but pretty convoluted

Pseudo code:
If (`uname -r` = J06 && `uname -v` >= 14) || (`uname -r`= H06 && `uname -v` >= 25)
	SHELL_PATH=/usr/coreutils/bin/bash
	SANE_TOOL_PATH=/usr/coreutils/bin:${prefix}/bin
else
	SHELL_PATH=${prefix}/bin/bash
	SANE_TOOL_PATH=${prefix}/bin
endif	

I didn't deem it worth the effort. As mentioned it'd most likely still need stuff from /usr/local/bin

And someone wanting prefix somewhere else could still do
PATH=/usr/local/bin:$PATH make prefix=/my/local/install/of/git 
And so find what's need in either the 1st or 2nd path of PATH

Bye, Jojo
