Restrict -fno-sanitize=function to Clang/LLVM only

The base GCC version 6,x does not support this option.

#
# All library objects contain sccsid strings by default; they may be
# excluded as a space-saving measure.  To produce a library that does
# not contain these strings, delete -DLIBC_SCCS and -DSYSLIBC_SCCS
# from CPPFLAGS below.  To remove these strings from just the system call
# stubs, remove just -DSYSLIBC_SCCS from CPPFLAGS.
#
# The NLS (message catalog) functions are always in libc.  To choose that
# strerror(), perror(), strsignal(), psignal(), etc. actually call the NLS
# functions, put -DNLS on the CPPFLAGS line below.
#
# The YP functions are always in libc. To choose that getpwent() and friends
# actually call the YP functions, put -DYP on the CPPFLAGS line below.
#
# The Hesiod functions are always in libc. To choose that getpwent() and friends
# actually call the Hesiod functions, put -DHESIOD on the CPPFLAGS line below.
