  Log Message:
  -----------
  MinGW-W64 fixes

- libpthread requires iteration over multilibs, unlike the core, it
does not detect and build multilibs by itself.

- Disable parallel builds for mingw-w64 components; until mingw-w64 core
builds clean, I am not trusting it.

- Make the list of tools to build configurable

- Turn on multilib in x86_64 sample.

- Make warnings about tuple less redundant. As in, "one WARN is enough,
no need to shout it three times".

- Messages about various steps/substeps are more aligned with the rest
of the components.

- Use 'make' instead of ${make} to invoke the companion make just built,
if applicable.
