Hello,
Building rustc in a freshly-built sid chroot yields to:
error: failed to run custom build command for `rustc_llvm v0.0.0

These option seem to be coming from llvm-config-7 --cxxflags:

-Wno-unused-command-line-argument -Wno-unknown-warning-option -fPIC

-D__STDC_CONSTANT_MACROS -D__STDC_FORMAT_MACROS -D__STDC_LIMIT_MACROS
AIUI these shouldn't have been put there if the c++ compiler doesn't
support them?
(Replacing them with spaces by hand in the llvm-config-7 binary seems to
be avoiding the issue)
