w32: Use -static-libgcc to avoid linking to libgcc_s_sjlj-1.dll.
* src/Makefile.am (extra_ltoptions): New.
(libgcrypt_la_LDFLAGS): Use it.
--
Since gcc 4.8 there is a regression in that plain C programs may link
to libgcc_s.a which has a dependency on libgcc_s_sjlj.dll. This is
for example triggered by using long long arithmetic on a 32 bit
Windows (e.g symbol __udivdi3).
As usual the gcc maintainers don't care about backward compatibility
and declare that as some kind of compatibility fix and not as
regression from 4.7 and all earlier versions.
