Anyone know how to translate this configure test to uClibc:

# See whether gas has R_PPC_REL16 relocs.
AC_CACHE_CHECK(for R_PPC_REL16 gas support, libc_cv_ppc_rel16, [dnl
cat > conftest.s <<\EOF
	.text
	addis 11,30,_GLOBAL_OFFSET_TABLE_-. at ha
EOF
if AC_TRY_COMMAND(${CC-cc} -c $CFLAGS conftest.s 1>&AS_MESSAGE_LOG_FD); then
  libc_cv_ppc_rel16=yes
else
  libc_cv_ppc_rel16=no
fi
rm -f conftest*])
if test $libc_cv_ppc_rel16 = yes; then
  AC_DEFINE(HAVE_ASM_PPC_REL16)
fi
