MesaLib + llvm + ubuntu

[Patrick Welche <prlw1%cam.ac.uk@localhost>]

According to graphics/MesaLib/options.mk:

----------------------------
revision 1.54
date: 2017-03-20 23:59:01 +0000;  author: gdt;  state: Exp;  lines: +2 -2;  comm

Do not suggest llvm option on Darwin

With llvm, the build fails, as apparently llvm turns on including
multiple libraries that do not build.  (Until recently, this option
was not enabled by default, so this change is essentially omitting
Darwin from the change to default to llvm in i386/x86_64.)

Thanks to maya@ for explaining/suggesting.
----------------------------

I think I see the same on Ubuntu 16.04.2 LTS:

In file included from draw/draw_llvm.c:45:0:
./gallivm/lp_bld_intr.h:63:20: error: unknown type name 'LLVMAttribute'
                    LLVMAttribute attr);
                    ^

Add Linux to the
        ${OPSYS} != "SunOS" && ${OPSYS} != "Darwin"
list?


Cheers,

Patrick
