        <pre>This morning I was unable to compile a 32 bit mesa from git. 64 bit compiled
properly. This was on a 64 bit install of Arch Linux with multiarch enabled and
using gcc version 4.9.0 20140521 (prerelease) from the official repositories.


I've bisected the issue to this commit:

7a63bd960c33127dbce0e5802a7cda96dc011104
automake: correctly append the version-script

Here's my configure line for the build:

export PKG_CONFIG_PATH="/usr/lib32/pkgconfig"
export LLVM_CONFIG="/usr/bin/llvm-config32"

CFLAGS="-m32 -msse -msse2 -march=i686 -mfpmath=sse -mtune=generic -O2 -pipe"
