From bf900311b84185b01dd4d03c0ff6f3a6e0ade2ed Mon Sep 17 00:00:00 2001

Subject: [PATCH] bootstrap: Use gnulib-tool from PATH if available.
Some distributions such as GNU Guix include in their package for
gnulib a 'gnulib-tool' command under their $bindir
prefix (e.g. '/bin') for users to use, along the unmodified full
sources. The idea is that any wrapping or distribution modifications
for the *execution* of the script at run time is done on these
commands, while the rest of the source should be in their
pristine (unmodified) version. Adjust the 'gnulib-tool' discovery
mechanism to support such installation layout.
* build-aux/bootstrap (autogen) <gnulib_tool>: Prefer to use from
PATH, else from $GNULIB_SRCDIR/../../bin/gnulib-tool, else from
$GNULIB_SRCDIR/gnulib-tool. Invoke script via 'sh' from PATH, for
portability.
* gnulib-tool.sh (func_gnulib_dir): Honor GNULIB_SRCDIR to locate
gnulib's main directory.
(func_version): Explicitly invoke git-version-gen via 'sh' to avoid
relying on the exact location of 'sh' hard-coded in the script
shebang.
