SIGILL problems with Hurd port of GO in gcc-8, and rpctrace bugs.

[Svante Signell]

Hi,

It seems like the Hurd port of GO will be available in next upload of gcc-8.
I've put some go code/debug info/printouts from a failing test at:
http://darnasus.sceen.net/~gnu_srs/gccgo-8/index0_tests/

The only difference between the OK and nOK cases is the number of arrays. There
seems to be a memory issue/*context problem. pthread_create does not seem to be
the cuplrit, but who knows. 

Additionally the rpctrace output hangs hard at gsync_wait() both for the
./index0-out-reduced_OK.x and ./index0-out-reduced_nOK.x files.
Has rpctrace been thoroughly tested on multi-thread applications?

Please, give feedback on this if you have possibility, specifically the rpctrace
bug(s).
