At least some string tests do (string/test-string.h):
/* We are compiled under _ISOMAC, so libc-symbols.h does not do this
for us. */
#include "config.h"
#ifdef HAVE_CC_INHIBIT_LOOP_TO_LIBCALL
# define inhibit_loop_to_libcall \
__attribute__ ((__optimize__ ("-fno-tree-loop-distribute-patterns")))
#else
# define inhibit_loop_to_libcall
#endif
I'd expect string benchmarks to do similarly (possibly factoring this out
to a separate header). That's much better than building them without
_ISOMAC and so getting *all* the internal header pieces.
