This patch to libgo uses DejaGNU when testing a cross-compiler.  The
shell script is simpler but only works for a native configuration.
Bootstrapped and ran Go testsuite on x86_64-unknown-linux-gnu.
Committed to mainline.  This should fix PR 56017.

This is a target library, so you need to check build != host to detect
building with a cross-compiler.

Andreas.

Argh.  Thanks.  Fixed like so.
