Change detection for the gnu_inline attribute.
According to the GCC documentation:
"This attribute is available in GCC 4.1.3 and later. It is available
if either of the preprocessor macros __GNUC_GNU_INLINE__ or
__GNUC_STDC_INLINE__ are defined."
We don't keep the gcc granularity up to the minor number so it's
better to use the documented way. Current clang defines both
macros.
