Aha - ok, I've had the same problem! I've tried injecting it many ways
and it doesn't work due to the intersection of libgcc_s and glibc.

Efraim - can you successfully run programs that link against glibc? As
in anything that uses os/user, net, etc? Running the tests as part of
your build is a big way to pick up on this, I've added the following to
my go-1.4.3 attempts in my build steps:

               
 ;; these all have specific file locations they look for
 ;; or in the case of exec_test resets the environment
 ;; before executing binaries they expect.
 (for-each delete-file '("src/net/multicast_test.go"
                                "src/net/parse_test.go"
                                "src/net/port_test.go"
                                "src/os/exec/exec_test.go"))
 (substitute* "src/os/os_test.go"
   (("/bin/pwd") (which "pwd"))
   (("/usr/bin") (dirname (which "pwd")))
   (("TestHostname") "areturn"))
 
 ;; Disable the unix socket test
 (substitute* "src/net/net_test.go"
   (("TestShutdownUnix") "areturn"))
 
 (substitute* "src/net/lookup_unix.go"
   (("/etc/protocols") (string-append iana "protocols")))
 
 ;; ParseInLocation fails the test
 (substitute* "src/time/format_test.go"
   (("TestParseInSydney") "areturn"))
 
 (substitute* "src/time/zoneinfo_unix.go"
   (("/usr/share/zoneinfo/") tz))
 
 ;; exec.Command on os.Args[0] from go run for whatever
 ;; reason doesn't work right now. libgcc_s.so link
 ;; missing crap occurs here as well, this may require
 ;; that 6l-wrapper for go run to work.
 (substitute* "src/syscall/syscall_unix_test.go"
   (("TestPassFD") "areturn"))

 (substitute* "src/cmd/6l/asm.c"
   (("char linuxdynld.*$") (string-append "char linuxdynld[] = \"" ld-linux "\";\n")))

I'll be trying this later with your packages.

I'd really hesitate on packaging this without runnning the tests, as
there are lots of ugly corner cases in go's build system.
