I am impressed you spotted this. Yes, according to the cpu manual
(Moxa Art ARM), it does say W1. So I tried this only to test. Even I
know -Wl is the correct way. Here is the correct config.log:

-------------------------
This file contains any messages produced by compilers while
running configure, to aid debugging if configure makes a mistake.

It was created by curl configure -, which was
generated by GNU Autoconf 2.64. Invocation command line was

  $ ./configure --disable-shared --disable-ares --disable-cookies
--disable-crypto-auth --disable-ipv6 --disable-verbose
--without-libidn --without-zlib --disable-ldap --disable-thread
--disable-shared --host=arm-elf --without-ssl --without-libssh2
