libvixl: remove per-target compiler flags

We are already including -D__STDC_LIMIT_MACROS in the global CXXFLAGS,
so it makes sense to do the same for -D__STDC_CONSTANT_MACROS and
-D__STDC_FORMAT_MACROS instead of limiting that to libvixl.

The -Wno-sign-compare option can also be removed since GCC 4.6 is not
supported anymore.
