cross-compiling to mingw32

[Simon Josefsson]

I'm trying to get GnuTLS working under mingw32 again, but I can't seem
to get libgcrypt 1.2.2 to build.  libgpg-error 1.1 built fine.  The
cipher/ and src/ directories build fine, but the tests/ fails.  The
resulting library isn't usable, it seems all symbols are prefixed with
an unnecessary '_' if I run 'nm' on it.  Any ideas?

Building libgsasl against the generated libgcrypt fails with similar
errors:

i586-mingw32msvc-gcc -g -O2 -o test-gc-hmac-md5.exe test-gc-hmac-md5.o  ../gl/.libs/libgl.a -L/usr/local/w32root//lib /usr/local/w32root//lib/libgcrypt.a /usr/local/w32root//lib/libgpg-error.a
/usr/local/w32root//lib/libgcrypt.a(mpi-bit.o): In function `gcry_mpi_rshift':
/home/jas/src/libgcrypt-1.2.2/mpi/mpi-bit.c:206: undefined reference to `__gcry_mpih_rshift'
/usr/local/w32root//lib/libgcrypt.a(mpi-div.o): In function `_gcry_mpi_tdiv_qr':/home/jas/src/libgcrypt-1.2.2/mpi/mpi-div.c:223: undefined reference to `__gcry_mpih_lshift'

Libgsasl without libgcrypt builds fine and work fine from both
self-tests and on Windows, so I have confidence in the compiler.  I'm
using current mingw32 from Debian testing.

Build log of libgcrypt 1.2.2 below.

Thanks!
