Jakub Jelinek 701e1b9406 gotools: Workaround non-reproduceability of automake 
The regen bot recently flagged a difference in gotools/Makefile.in.
Trying it locally, it seems pretty random
for i in `seq 20`; do PATH=~/automake-1.15.1/bin:~/autoconf-2.69/bin:$PATH automake; echo -n `git diff Makefile.in | wc -l`" "; done; echo; for i in `seq 20`; do
+PATH=~/automake-1.15.1/bin:~/autoconf-2.69/bin:$PATH setarch x86_64 -R automake; echo -n `git diff Makefile.in | wc -l`" "; done; echo;

I'm not familiar with automake/m4 enough to debug that, so I'm
instead offering a workaround, with this patch the order is deterministic.

2024-04-15  Jakub Jelinek  <jakub@redhat.com>

	* Makefile.am (install-exec-local, uninstall-local): Add goals
	on the else branch of if NATIVE to ensure reproducibility.
	* Makefile.in: Regenerate.

README 

This directory builds tools used by people working in the Go language.
The source code for these tools lives in libgo/go/cmd, where it is
copied from the master gofrontend repository.  This directory contains
only the configure/Makefile instructions required to build the tools.

This directory builds two programs for general use: go and gofmt.  It
also builds one program for internal use by the go tool: cgo.  For
more information on these tools see the doc.go files in the relevant
source code, which can also be seen hosted at golang.org:
