After trying some other approaches (including adding libgo.spec,
similar to java soultion), I think that attached patch is the most
straight-forward solution to enable full IEEE compliance to Go
language.

* config/alpha/alpha.c (alpha_option_overrride): Default to
full IEEE compliance mode for Go language.
Tested on alphaev68-pc-linux-gnu, where it fixes all go testsuite
failures that depend of full IEEE compliance.
OK for mainline?
Uros.
