intl: reintroduce unintentionally disabled optimization
HAVE_BUILTIN_EXPECT macro was removed by commit glibc-2.14-280-g3ce1f29, but then its use was unintentionally reintroduced during merge with GNU gettext 0.19.3 by commit glibc-2.20-324-g6d24885, effectively disabling all optimization based on __builtin_expect. As intl files are also part of GNU gettext, HAVE_BUILTIN_EXPECT macro cannot be removed, so define it unconditionally in config.h.in instead. [BZ #19512] * config.h.in (HAVE_BUILTIN_EXPECT): New macro.
