databases/mariadb101-server: Fix i386, GSSAPI & Engine build issues
- Add USES=compiler:c++11-lib
- Use both deprecated -DPLUGIN_${engine} and new -DWITHOUT_${engine} to disable engines (fixes engines not being disabled)
- Add IGNORE for GSSAPI_BASE on FreeBSD < 10, version is too old
- Add IGNORE for TokuDB, upstream not supported on 32-bit platforms
- Add IGNORE on i386, currently broken with clang [1]
