I've been seeing this bug crop up in many circles: https://bugzilla.redhat.com/show_bug.cgi?id=1099282

Many folks like to use clang as their primary compiler for various reasons, is there anyone who knows a workaround or fix?

If you're building RPMs locally, you can drop your own definition of __global_cflags into '~/.rpmmacros':

%__global_cflags -O2 -g ..etc..

If you are building a package that uses an autoconf-generated configure script, then simply setting CFLAGS before running configure should be enough, eg:

CFLAGS="$( rpm --eval '%{__global_cflags}' | sed 's/-fstack-protector-strong//' )" \ ./configure

Rich.
