What steps will reproduce the problem?
1. set $CC to clang & $CXX to clang++
2. follow the build instructions from http://golang.org/doc/install/source
3. notice the issue after running ./all.bash

What is the expected output?
net
os/user
testing
testing/iotest
testing/quick
crypto/x509
net/textproto

What do you see instead?
testing
testing/iotest
testing/quick
net
os/user
# os/user
lookup_unix.go:64: cannot use _Ctype_size_t(bufSize) (type C.size_t) as type C.ulong in
function argument
crypto/x509
net/textproto

Which compiler are you using?
installed llvm, clang, & clang++ from official repo
$ clang --version
clang version 3.3 (tags/RELEASE_33/final)
Target: x86_64-unknown-linux-gnu
Thread model: posix

Which operating system are you using?
Arch Linux installed from the 2013.10.01 release
$ uname -a
Linux hostname 3.11.6-1-ARCH #1 SMP PREEMPT Fri Oct 18 23:22:36 CEST 2013 x86_64
GNU/Linux

Which version are you using?  (run 'go version')
after setting $CC & $CXX to gcc & g++ and grabbing a fresh clone I successfully
built Go and it reports:
$ go version
go version go1.1.2 linux/amd64

Please provide any additional information below.
When I built Go using gcc it ran tests after building the packages. When I failed to
build using clang it seemed to successfully build all the other packages but kicked me
back to the prompt afterward with no testing or additional output.
