There is nothing special:
configure --prefix=/usr --with-cpu=power8 --enable-add-ons
make
make -k check

I'm using GCC 4.8.4.

It seems we already have some testcases doing that:
$ find . -type f \( -name 'test-*' -o -name 'tst-*' -o -name 'bug*' \) \
  | xargs grep -n libc-internal.h
./stdio-common/tst-printfsz.c:5:#include <libc-internal.h>
./stdio-common/tst-unlockedio.c:23:#include <libc-internal.h>
./stdio-common/test-vfprintf.c:28:#include <libc-internal.h>
./stdio-common/tst-sprintf.c:5:#include <libc-internal.h>
./stdio-common/bug21.c:2:#include <libc-internal.h>
./stdio-common/tst-printf.c:29:#include <libc-internal.h>
./string/tst-endian.c:6:#include <libc-internal.h>
./misc/tst-error1.c:6:#include <libc-internal.h>
