Subject: Modified the SUFFIXES pseudo targets so that we remove all default
 suffixes and explicitly declare all the ones we're using for LLVM. This
 quickly cancels many of GNU Make's implicit rules and reduces build time. The
 only caveat is that any new suffixes may need to be explictly added to the
 .SUFFIXES pseudo target.

Removed the -only-static option as it is no longer used.
