[bug#28226] Build go with gccgo

[Efraim Flashner]

[-- Attachment #1.1: Type: text/plain, Size: 493 bytes --]

I need some help testing this on x86_64, I did all the building and
testing on aarch64. It turns out there's a known issues in the cgo
implementation that causes the test suite to fail on aarch64. With this
patch set I was able to build gccgo@7 -> go@1.7 -> lfam's syncthing.

I don't know what these patches do, I was just trying to apply them in
order (1, 2, 3)

Should I follow a different order ?

I would have attempted to build this thing

I git pulled on master right now ( 12 september) and created a branch for
thhese patches and git am'ed there

I've reattached the patches, seems they don't apply cleanly anymore
