Subject: [PATCH] Add -mxgot flag to td_scheme on MIPS64

This fixes "relocation truncated to fit ..." error on final linking. It should
not introduce a lot of overhead since the code is used only in network
communications.

This errors appears sometimes and I do not know exact conditions, I think it is
related to large size of an object file with the schema.

More docs see at https://gcc.gnu.org/onlinedocs/gcc/MIPS-Options.html#index-mxgot-1
