Log Message:
split MKLLVM into MKLLVM and MKLLVMCMDS, like MKGCC and MKGCCCMDS:

- only build clang or clang-tblgen if MKLLVMCMDS != "no"
- move HAVE_MESA_VER earlier so we can detect mesa 18 and enable
  MKLLVM on platforms that need it
- move the clang commands and headers into llvmcmds group
- only build the clang specific LLVM libraries if MKLLVMCMDS != "no"

much of this work came from maya@'s github commit
f90685c11d4460d3098fa35f48b58d1893e974e0, reworked for HAVE_MESA_VER
and llvmcmds vs MKCLANG.

build tested on several platforms and on amd64 and i386 with several
different build options (clang build, gcc build, gcc build with llvm
libs).
