cmd/ld: compilerrt_abort_impl not defined for misc/cgo/test on freebsd

[minux]

CL 114420043 broke freebsd/amd64 builder with this error message:

ok   _/tmp/gobuilder/freebsd-amd64-b613f2acdf69/go/misc/cgo/test 1.538s
# testmain
_/tmp/gobuilder/freebsd-amd64-b613f2acdf69/go/misc/cgo/test(.text):
compilerrt_abort_impl: not defined
FAIL _/tmp/gobuilder/freebsd-amd64-b613f2acdf69/go/misc/cgo/test [build failed]
Build complete, duration 5m17.708335978s. Result: error: exit status 1

(log: http://build.golang.org/log/ae502c5cfde2c7b734feb986ccb344ff69e059ba)

That CL fixes a real bug that practically disables that "symbol not defined"
diagnosis, so there must be latent bug in cmd/ld.

According to https://llvm.org/svn/llvm-project/compiler-rt/trunk/lib/builtins/int_util.c,
the symbol seems to be marked hidden, so that's probably the reason why cmd/ld
thinks it's undefined.

Comment 1:

This looks to be the inverse of https://golang.org/issue/4273

Comment 2:

it's strange that the test introduced in that issue didn't fire,
so perhaps it's another problem?
as mentioned in that issue, if you could upload a copy of the
work directory for:
go test -c -x -work -ldflags "-linkmode internal" ../misc/cgo/test
that will be a great help.

Comment 3:

I'm not in front of the machine, but when I ran it with -x, it failed at 6l
-linkmode=internal
