I tried something to a similar effect, I manually changed config.h accordingly (see other email of mine) and rebuilt dirfd.o, rebuilt libcoreutils.a, relinked rm:
Didn't work :-(

In case it matters: I'm using 
./configure --prefix=/usr/local --enable-install-program=arch,hostname --without-gmp CFLAGS="-O0 -g"
