Clang support for gnu_inline attribute
Clang also supports the gnu_inline attribute and the
__GNUC_STDC_INLINE__ macro (C99 semantics). However, it reports as
GCC 4.2 compatible (__GNUC_MINOR__ / __GNUC__) and thus the current
defines do not think it can support this.
Add clang as an alternative for this support. Documentation shows that
this attribute is supported since at least Clang 8.
