gotools patch committed: Fix for non-bootstrap case

[Ian Lance Taylor]

[-- Attachment #1: Type: text/plain, Size: 549 bytes --]

When not bootstrapping, the newly built Go compiler is not passed down
to the Go tools as GOC.  This patch changes the gotools Makefile to
use GOC_FOR_TARGET for a native build.  I also set MOSTLYCLEANFILES.
Bootstrapped on x86_64-unknown-linux-gnu.  Committed to mainline.

* Makefile.am (GOCOMPILER): Set to GOC or GOC_FOR_TARGET depending
on whether this is a native build or not.
(GOCOMPILE, GOLINK): Use $(GOCOMPILER) instead of $(GOC).
(MOSTLYCLEANFILES): Define.
* Makefile.in: Rebuild.
