[PATCH] Make GNUInline consistent with whether we use traditional GNU inline semantics.

[Richard Smith]

I believe your change to not define `__GNUC_GNU_INLINE__` will break recent versions of glibc, which test for the definition of either that or `__GNUC_STD_INLINE__` to determine whether `__attribute__((__gnu_inline__))` is available: https://sourceware.org/git/?p=glibc.git;a=blob;f=misc/sys/cdefs.h;h=99e94cce869572b724df6b5b8c847cc38a0b3a57;hb=HEAD#l331
