What did you do?

	@ls -la build

What did you expect to see?

A successful build without error.

What did you see instead?

Error thrown is:

building for linux/armv6l ...
# runtime/cgo
gcc: error: unrecognized command-line option '-marm'
make: *** [Makefile:24: release_files] Error 1

I think the GOARCH is calling the wrong gcc option:
https://gcc.gnu.org/onlinedocs/gcc/ARM-Options.html#index-march-2

[seankhliao]

marm is a valid flag: https://gcc.gnu.org/onlinedocs/gcc/ARM-Options.html#index-marm

You'll need a valid gcc installation for arm (https://bugzilla.redhat.com/show_bug.cgi?id=1409962)
