Subject: Add an autoconf option for turning on -gsplit-dwarf by default when
 building llvm. This saves quite a bit of time and space when linking. Please
 report any problems via bugzilla.

Caveats:

a) This will only work on linux
b) This requires a fairly new binutils
c) This requires a fairly new gdb
