Hello Mips porters,
can anyone advise how to process on this FTBFS?

You have to find the commands that are generating
/tmp/ccuNHoVF.ltrans0.ltrans.o
They are not shown in the logs.
The error message is correct, '__gnu_local_gp' cannot be used in
position independent code. If the offending file is being generated by
gcc/g++ then you should be able to show the command line that led to its
being created.
But -fPIC is used everywhere AFAICS (except for the linking call).
It should probably be used for linking too. Why isn't it?
If the linking step is generating /tmp/ccuNHoVF.ltrans0.ltrans.o, this
could explain your problem.
It also happens on mipsel.
Not surprising, it is not an endian specific issue.
Thanks,
Eduard.
