libgsasl: add mandatory dependency on wchar

libgsasl needs wctomb, if not available it will define it to
rpl_wctomb. However, as there is no rpl_wctomb implementation, the .so
ends up with an undefined reference to wctomb.

This will cause linker errors for packages trying to use it such as
msmtp:
/home/peko/autobuild/instance-0/output/host/bin/../microblazeel-buildroot-linux-uclibc/sysroot/usr//lib/libgsasl.so:
undefined reference to `wctomb'
