# The sixgill plugin uses some gmp symbols, including some not exported by
# cc1/cc1plus. So link the plugin statically to libgmp. Except that the
# default static build does not have -fPIC, and will result in a relocation
# error, so build our own. This requires the gcc and related source to be
# in $root_dir/gcc-source.
