If you did:

	make prefix=$HOME all
        make prefix=/usr install

then the second step needs to notice that the gitexecdir computed and
stored in exec_cmd.o in the first step is now invalid, and needs to
recompile the file.  The whole purpose of GIT-BUILD-OPTIONS is to detect
such a case---doesn't your change defeat it?
