[Mesa-dev] [PATCH] mesa: make makedepend an hard requirement

Currently makedepend is used by the Mesa Makefile-based build system,
but not required.

Unfortunately, not having it makes dependency resolution non-existent,
which is a source of subtle bugs, and is a rarely tested
configuration, since all Mesa developers likely have it installed.

Furthermore some idioms require dependency resolution to work at all,
such as making headers depend on generated files.

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