			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
    [...]
    $ echo $?
    0
