To quote Dan Nicholson :
"In fact, when I wrote configure.ac originally, I wanted it to be a hard
requirement and assumed that AC_PATH_PROG would error by default if it
didn't find the program."
I have been updating and building mesa a few times per week. More often than
not, this just resulted in segfault at runtime, and I had to make clean and
do a full build again. This was simply because I did not have makedepend
installed, and parts of the tree were not rebuilt when they should.

dnl Our fallback install-sh is a symlink to minstall. Use the existing
dnl configuration in that case.
