So I've fixed my header problems (I think) by supplying scan-build with
--use-cc to point to my cross compiler, and I've hacked
clang/lib/Frontend/InitHeaderSearch.cpp to remove the system default paths
and then AddPath() paths to my alternate headers used by my cross compiler
which was built with --with-sysroot.

I'm still stuck on this
    #error  This fenv header and set of APIs is intended for the ARM (with
VFP) architecture only.

Setting CLANG to
CLANG=clang -ccc-host-triple arm-apple-darwin
Gives me the above error:
cannot find 'clang-cc' in 'clang' command

Trying the older revision  r72538.did not help solve the problem.

Is there some way I could hack the source directly to force the host triple
to arm-apple-darwin? Where would I do that?
Can I hard code this directly in Driver.cpp
const HostInfo *Driver::GetHostInfo(const char *TripleStr)


Thanks
