Interesting issue with gccgo

[Bryan Hundven]

In response to:
https://github.com/crosstool-ng/crosstool-ng/issues/96

I've made a diff that does the following:

This is a workaround, and the problem should really be fixed upstream in gcc.

Once that workaround is in place, the build ultimately fails in
finalize when it's trying to strip binaries:

I kind of expect this, as -go and -gofmt are tools for the target, not the host.

I'm just not sure what should be done in this case.

Any suggestions?
