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
