In addition to what Pierre-François suggested, you might consider
creating an update hook in your build server's repository [1] which
would check the commits pushed to it and rejecting them if it finds any
of the build script files appears in any of these commits.
Writing such a hook script requires knowledge of Git's plumbing commands
but it's definitely doable.
The basic idea is that an update hook's script is passed several
parameters which are: the name of the reference (branch, most
typically) to be updated, SHA-1 names of the commit at which the
reference is currently pointing and the commit it would point at should
the update suceed. So you get the list of SHA-1 names of all the
commits sent to update that reference calling
git rev-list $new_commit ^$old_commit
You then inspect each of them by calling
git ls-tree --name-only -r $commit
which returns a list of all the files contained in the commit,
and try to spot offending files in this list.
If any is found, exit the script returning a non-zero exit code to
prevent that reference from updating, otherwise exit with a zero exit
code.
An example shell script (untested):
----8<----
#!/bin/sh
set -eu
ref="$1"
old="$2"
new="$3"
buildscripts="$GIT_DIR/buildscripts"
git rev-list "$new" ^"$old" |
while read c; do
git ls-tree --name-only -r "$c" |
grep -q -F -f "$buildscripts" && exit 1
done
exit 0
----8<----
The file named "buildscripts" located in the repository's root
directory should contain names of your build scripts, relative
to the project's root, like this:
dir1/dir2/build.sh
dir1/Makefile
dir3/Makefile.am
and so on.
