There are two problems building micropython for Blackfin. The first is
some printf format specifier warnings/errors that seem to be triggered
only for that architecture/compiler. This could be worked around by
specifying CFLAGS=-Wno-error=format.
The second problem is that libffi doesn't provide the closure
implementation on Blackfin. There is no known workaround for this issue.
For now disable micropython on Blackfin.

Rather than specifying architectures that do not have explicit support
in micropython invert the logic and set MICROPY_GCREGS_SETJMP=1 if the
architecture does not have explicit support. MIPS is listed as being
supported but this support consists of automatically defining
MICROPY_GCREGS_SETJMP 1 based on __mips__ being defined.

This patch applies an upstream patch to fix a compile error like this
one:
modffi.c: In function 'ffifunc_call':
modffi.c:358:25: error: cast from pointer to integer of different size
[-Werror=pointer-to-int-cast]
values[i] = (ffi_arg)a;
This error can be highlighted when building micropython for MIPS64 n32
because ffi_arg is 64-bit wide and the pointers on MIPS64 n32 are 32-bit
wide, so it's trying to case an integer to a pointer (or vice versa) of
a different size. We should cast first the pointer (or the integer) to a
pointer sized integer (intptr_t) to fix that problem.
This patch was merged upstream as a result of this pull request:
https://github.com/micropython/micropython/pull/1471

These architectures don't have explicit exception handling support in
micropython but can use the setjmp fallback behaviour instead.
