  Log Message:
  -----------
  Pass FOR_BUILD flags when building the pass-1/2 core GCC.

Current build passes {CFLAGS,LDFLAGS}_FOR_HOST - which breaks canadian cross
(e.g. tried building for x86_64-unknown-linux-uclibc host). This dates
back to the days of yore when CFLAGS were set directly in the do_gcc_core_backend
(and that function is used as the final gcc's backend).

do_gcc_core_backend is now passed with CFLAGS/LDFLAGS to use, so let
the pass-1/pass-2/final-for-build steps pass the appropriate flags.

    M config/debug/duma.in

  Log Message:
  -----------
  Disallow dmalloc for bare metal.

In case of bare metal, newlib is built without any syscalls,
and dmalloc fails to link with undefined references to _exit,
fstat, open, sbrk and so on.

Same for DUMA: depends on <memory.h>, not available with newlib.

  Remove a broken sample.

We don't have a sample that builds the required toolchain (i586-mingw32msvc).

  Log Message:
  -----------
  Enable posix threads in x86_64-w64-mingw32.

This enables the resulting toolchaing to be used to build a canadian
cross to x86_64-pc-linux-gnu target. Unmark that sample as broken,
it now builds successfully.

It is likely that it is affected by issue #483, too - I see the
resulting gcc executable has a DLL dependency on libiconv-2.dll,
which is only installed into .build/.../buildtools. This will be
investigated/fixed separately.
