Go 1.6 pass regress on openbsd/386 and openbsd/amd64. Also stop exporting
environ and __progname from cgo, since these symbols are no longer required
by libc.
sigreturn syscall is going away in future versions of OpenBSD and its
use for Go is already broken due to the trampoline return checks. Instead
just return directly from the signal trampoline (as we have always done
for Go openbsd/amd64).
Also fix a bug in the Go openbsd/386 linker, which results in symbols in
the dynamic symbol table being emitted with a size of zero. With a current
ld.so, this results in symbol mismatch warnings.
Unbreaks the Go port on openbsd/386, however it still fails to pass regress
due to the PT_TLS changes.
some ports that used to depend on GO15VENDOREXPERIMENT=1 need 1.6 or they
won't build as the usage of that variable has been removed in their Makefiles.

Clear user's environment with SETENV and provide MODGO_ENV for adding variables
to environment and MODGO_GOPATH for altering GOPATH.

- raise minimum amount of memory in the ulimit check to 5GB (the no_bootstrap
flavour uses even more, usually crashing the kernel on my 8GB workstation if
I try to build it there)

"Go's crypto libraries passed certain parameters unchecked to the
underlying big integer library, possibly leading to extremely
long-running computations, which in turn makes Go programs vulnerable to
remote denial of service attacks. Programs using HTTPS client
certificates or the Go SSH server libraries are both exposed to this
vulnerability.
This is CVE-2016-3959 and was addressed by this change:
https://golang.org/cl/21533
Thanks to David Wong for identifying this issue."
