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:
CFLAGS-libresolv += -fstack-protector-strong
CFLAGS-libnss_dns += -fstack-protector-strong
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.
Please inform the customer that this is outside the scope of support. If they are rebuilding glibc based on RHEL and they don't use a compiler with SSP enabled then they will need to patch their sources.
