[Mesa-dev] [PATCH] configure.ac: always define __STDC_CONSTANT_MACROS

[Oded Gabbay]

The ISO C99 standard (7.18.4) specifies that C++
implementations should define UINT64_C only when
__STDC_CONSTANT_MACROS is defined.

ecause we now use UINT64_C in our cpp files (since commit
208bfc493debe0344d0b9cb93975981f14412628), we need to add this define.

This also solves compilation errors with GCC 4.8.x on ppc64le machines.
