[Mesa-dev] [PATCH] gallium: fix build failure on powerpcspe

[Julien Cristau]

From: Roland Stigge <stigge at antcom.de>

In the case of powerpc, mesa activates some altivec instructions
that are unknown on the powerpcspe architecture (see
https://wiki.debian.org/PowerPCSPEPort), causing a build failure as the
'vand' opcode is not recognized by the assembler.

This patch fixes this by preventing the PPC-specialcasing in case of
powerpcspe (__NO_FPRS__ is only defined there).
