An user is working on cross compilation of glibc.

  This pseudo patch is required in resolv/Makefile, for the user setup
with recent rhel7 glibc:

+ifeq (yes,$(have-ssp-strong))
 CFLAGS-libresolv += -fstack-protector-strong
 CFLAGS-libnss_dns += -fstack-protector-strong
+endif

then, the user should just do something like this:

echo libc_cv_ssp=no >> config.cache
echo libc_cv_ssp_strong=no >> config.cache

as apparently the user is using a cross compiler built with --disable-libssp.
