RE: pygccjit give back

Yes I am aware of that.
There is a -mips1 flag in compile line.
I am not sure what is the reason for this.

Additionally I have traced back changes that caused this new issue and they are first introduces with gcc-5_5.2.1-13 version:

Building gcc-5 from source without those changes resolved this issue on mips/mipsel.

It should be introduced by enable fpxx by default.
As ldc1/sdc1 are introduced from MIPS II.
So, maybe somewhere, `-mips1' option is used.
