      Description

      The xkbcommon.pri doesn't appear to respect any mkspec-specified build argument.

      Steps to reproduce:
      1. configure Qt 5.1.0 beta with:
      ./configure -debug -prefix $PWD/qtbase -platform linux-g++-32 -nomake examples -nomake docs -qt-xkbcommon
      2. run:
      make

      Expected result:
      The build succeeds

      Actual result:
      The build fails with:

      In qtbase/src/3rdparty/xkbcommon.pri
      there is this line:
      QMAKE_CFLAGS = -std=gnu99 -w

      If one adds -m32 the build runs fine and 32-bit object files are created. Without adding -m32 it produced 64bot .o files and then later errored out when linking was attempted due to the conflicting architectures.
