Disable __USE_EXTERN_INLINES for clang

Browse Source 
clang does not allow to redefine attributes after function declaration.
Although it work for external usage, its breaks the build for internal
symbol that glibc provides as optimization (for instance bsearch
with stdlib-bsearch.h or __cmsg_nxthdr).

Disable such optimization for clang while building glibc.
