midipix target implementation: finalize preliminary biarch support.
+ set default arch to m32/m64 for the i686- and x86_64- toolchains, respectively.
+ temporarily disable SEH for the i686-nt32-midipix target; this is needed since
the 32-bit PE assembler rejects .seh_proc, meaning that currently we cannot
even have 32-bit SEH support as a stub (adding the necessary assembler support
should be easy, as it already exists for the 64-bit Windows targets).
signed-off by Z. Gilboa; see copying.midipix (9cd0746c) for additional information.
