Description
What steps will reproduce the problem?
If possible, include a link to a program on play.golang.org.
1. Build on armel and run test
What is the expected output?
ok sync/atomic
What do you see instead?
SIGILL: illegal instruction
PC=0xc233c

Which compiler are you using (5g, 6g, 8g, gccgo)?
5g
Which operating system are you using?
armel (Little-endian ARM, e.g. GOARM=5)
Which version are you using? (run 'go version')
go1
Please provide any additional information below.
The build variables are set using this logic:
ifeq ($(DEB_HOST_ARCH_CPU), i386)
GOARCH := 386
GOPREFIX := 8
else ifeq ($(DEB_HOST_ARCH_CPU), amd64)
GOARCH := amd64
GOPREFIX := 6
else ifeq ($(DEB_HOST_ARCH_CPU), arm)
GOARCH := arm
GOPREFIX := 5
ifeq ($(DEB_HOST_ARCH), armel)
GOARM := 5
else ifeq ($(DEB_HOST_ARCH), armhf)
GOARM := 6
else
$(error unrecognized arm architecture $(DEB_HOST_ARCH)!)
endif
else
$(error unrecognized instruction set $(DEB_HOST_ARCH_CPU)!)
endif
It looks like some GOARM=6 code has creeped into GOARM=5 branch, but I could be mistaken.
