            Bug ID: 80964
           Summary: cross-gotools are not executable on host system
           Product: gcc
           Version: 8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: go

  Target Milestone: ---

I don't know if that is a bug or a feature,
but I use a build spec like this one:

../gcc-trunk/configure --prefix=/home/ed/gnu/arm-linux-gnueabihf-linux64
--target=arm-linux-gnueabihf --enable-languages=all --with-arch=armv7-a
--with-tune=cortex-a9 --with-fpu=vfpv3-d16 --with-float=hard

Note: Recently "all" was changed to include go as well.

Everything builds cleanly, except that the executables
bin/arm-linux-gnueabihf-go and bin/arm-linux-gnueabihf-gofmt
are built for the target system and not for the host, as every other
program in the bin folder:
