This should be already handled by the code on lines #176 and #439:
    http://crosstool-ng.org/hg/crosstool-ng/file/7a5ee8d36a1d/scripts/build/cc/gcc.sh#l176

176    for tmp in ARCH ABI CPU TUNE FPU FLOAT; do
177         eval tmp="\${CT_ARCH_WITH_${tmp}}"
178         if [ -n "${tmp}" ]; then
179             extra_config+=("${tmp}")
180         fi
181     done

(same code on line #439 for the final gcc)

Isn't it the case for you?
