Message-ID: <a79e9e9f50410721d85747b03559d55be98bca20.1739478347.git.me@ttaylorr.com>

```
Back in 728b9ac0c3 (Makefile(s): avoid recipe prefix in conditional
statements, 2024-04-08), we prepared our Makefiles for a forthcoming
change in upstream Make that would ban the recipe prefix within a
conditional statement by replacing tabs (the prefix) with eight spaces.

In b9d6f64393 (compat/zlib: allow use of zlib-ng as backend,
2025-01-28), a handful of recipe prefix characters were introduced in a
conditional statement ('ifdef ZLIB_NG'), causing 'make' to fail on my
system, which uses GNU Make 4.4.90.

Remove the recipe prefix characters by replacing them with the same
script as is mentioned in 728b9ac0c3.

Yikes.  Thanks for fixing it so quickly.

Oh, that's a change I wasn't aware of in Make. The patch looks obviously
good to me in that context, thanks for fixing!
