"no_c99_libc_has_function" would be incorrect: before we switched to
target hook implementation of checking the presence of builtin
functions, we had for hpux:

/* ia64 HPUX has the float and long double forms of math functions.  */
#undef TARGET_C99_FUNCTIONS
#define TARGET_C99_FUNCTIONS  1

And since now we assume that by default c99 functions are present, the
correct version of the hook would be exactly the default one.

That's right, it is committed:
