[MLton-commit] r5865

[Matthew Fluet]

Drop '-mtune=opteron' and '-mcpu=opteron' flags to gcc on amd64 (when
compiling runtime and when invoking gcc from mlton).

Unify '-m32 -mcpu=v8 -Wa,-xarch=v8plusa' flags to gcc on sparc (when
compiling runtime and when invoking gcc from mlton).  This drops the
'-mcpu=ultrasparc' flag (which was passed via '-target-cc-opt
solaris'), which appears to be incompatible with '-mcpu=v8', according
to the gcc documentation.
