This patch to gotools/configure.ac fixes the build to build the tools
when host_alias = target_alias, or, in other words, when the system
for which we are building code is the same as the system where that
code will run.  The earlier test of cross_compiling effectively tested
whether build_alias and host_alias were different, which is not the
same thing when doing a Canadian Cross.  This is for PR 80964.
Bootstrapped on x86_64-pc-linux-gnu (there are no tests for this code,
which is unfortunate).  Committed to mainline.
