From the question raised on golang-nuts:
https://groups.google.com/forum/#!topic/golang-nuts/SJn48BkCUqA

What steps will reproduce the problem?
1. CFLAGS=" -WILL " LDFLAGS=" -BREAK " ./all.bash
2.
3.


What is the expected output?

# Building C bootstrap tool.
cmd/dist
gcc: error: unrecognized command line option ‘-WILL’


What do you see instead?
# Building C bootstrap tool.
cmd/dist

# Building compilers and Go bootstrap tool for host, linux/amd64.
lib9
libbio
libmach
misc/pprof
cmd/addr2line
cmd/nm
cmd/objdump
cmd/pack
cmd/prof
cmd/cc
cmd/gc
[...]


Which compiler are you using (5g, 6g, 8g, gccgo)?
n/a


Which operating system are you using?
# cat /etc/*release
LSB_VERSION=base-4.0-amd64:base-4.0-noarch:core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch
Red Hat Enterprise Linux Workstation release 6.5 (Santiago)
Red Hat Enterprise Linux Workstation release 6.5 (Santiago)


Which version are you using?  (run 'go version')
go1.2.src.tar.gz


Please provide any additional information below.
Ideally these values would not only apply for the cmd/dist and bootstrapping, but
anywhere that CC is invoked on this system.

Since the CC value used for build of ./make.bash is persisted, it may be worth having an
optional CC_FINAL, in the case that CC was a build-time only explicit path.
