In GNU Make commit 07fcee35 ([SV 64815] Recipe lines cannot contain
conditional statements, 2023-05-22) and following, conditional
statements may no longer be preceded by a tab character (which Make
refers to as the recipe prefix).
There are a handful of spots in our various Makefile(s) which will break
in a future release of Make containing 07fcee35. For instance, trying to
compile the pre-image of this patch with the tip of make.git results in
the following:
$ make -v | head -1 && make
GNU Make 4.4.90
config.mak.uname:842: *** missing 'endif'. Stop.
The kernel addressed this issue in 82175d1f9430 (kbuild: Replace tabs
with spaces when followed by conditionals, 2024-01-28). Address the
issues in Git's tree by applying the same strategy.
When a conditional word (ifeq, ifneq, ifdef, etc.) is preceded by one or
more tab characters, replace each tab character with 8 space characters
with the following:
find . -type f -not -path './.git/*' -name Makefile -or -name '*.mak' |
xargs perl -i -pe '
s/(\t+)(ifn?eq|ifn?def|else|endif)/" " x (length($1) * 8) . $2/ge unless /\\$/
'
The "unless /\\$/" removes any false-positives (like "\telse \"
appearing within a shell script as part of a recipe).
After doing so, Git compiles on newer versions of Make:
$ make -v | head -1 && make
GNU Make 4.4.90
GIT_VERSION = 2.44.0.414.gfac1dc44ca9

This is to prepare for gitk i18n effort that makes gitk not a single file
project anymore. We may use subproject to bind git.git and gitk.git more
loosely in the future, but we do not want to require everybody to have
subproject aware git to be able to pull from git.git yet.
