Updated patch for the current lang/go

- Set CGO_ENABLED=3D1 unconditionally. CGO_ENABLED already defaults to 1 on=
 all
supported archs except ARM [1], so effectively this change just enables it =
on
ARM.

- Set GOARM from ARCH for ARM archs. The appropriate GOARM value is suppose=
d to
be chosen automatically when compiling on target hardware but on FreeBSD, i=
t is
always set to "5" due to the code [2] from a 4 years old commit. I don't kn=
ow
if "FreeBSD has broken VFP support." is still true, maybe a FreeBSD/ARM exp=
ert
can chime in on that.

QA:

Builds fine in poudriere on 12a, 12i and 11a but otherwise untested - lang/=
go
doesn't currently build in poudriere/qemu on amd64 hosts (comment #14) and
qemu-sbruno is marked as BROKEN on i386.=20
