mesa: use build flag to ensure stack is realigned on x86
Nowadays GCC assumes stack pointer is 16-byte aligned even on 32-bits, but that is an assumption OpenGL drivers (or any dynamic library for that matter) can't afford to make as there are many closed- and open- source application binaries out there that only assume 4-byte stack alignment. V4: fix comment and indentation V3: move all sse4.1 build flag config to the same location and add comment as to why we need to do the realign V2: use $target_cpu rather than $host_cpu and setup build flags in config rather than makefile https://bugs.freedesktop.org/show_bug.cgi?id=86788 Signed-off-by: Timothy Arceri <[email protected]> Reviewed-by: Matt Turner <[email protected]> CC: "10.4" <[email protected]>
