lzma fails to build on 10.6 i386 with gcc: no such instruction: `xgetbv'

[barracuda156]

Looks like it calls LLVM-specific assembler.

Or maybe the issue is that this is on CoreDuo (32-bit) and those instructions do not exist.

[kencu (Ken)]

the xgetbv instruction is not understood by the assembler being used.

[barracuda156]

Opened a ticket with upstream, since it is a clear regression: 22.01 builds fine as-is with no hacks, with a system compiler. Something got broken with detection of support for related instructions.
