Hi,
I'm setting up a CI for GNU bison. I'm using the bootstrap command
$ ./bootstrap --no-git --gnulib-srcdir="$GNULIB_SRCDIR"
but that later leads to a build failure:
$ make
...
CCLD src/bison
GEN doc/bison.help
/bin/bash: line 1: ./build-aux/move-if-change: No such file or directory
make[2]: *** [Makefile:13803: doc/bison.help] Error 127
The reason is that a symlink was committed:
move-if-change -> ../gnulib/build-aux/move-if-change
that hardcodes the location of the Gnulib repository.
The attached patch fixes it.

Subject: [PATCH] build: Don't hardcode the location of the gnulib directory.
* build-aux/move-if-change: Remove symlink.
* bootstrap.conf (gnulib_extra_files): Add build-aux/move-if-change.
