By default it will build i686-pc-mingw32 (32 bit mingw.org as per

make MXE_TARGETS=x86_64-w64-mingw32

you can also set this in settings.mk and optionally build multiple
targets.

There is no MXE_TARGETS variable in Makefile.  Using that you end up
with 32-bit results, nothing is built for 64-bit.

I'm referring to the multi-rebase branch, there's a fuller description here:

Perhaps you meant TARGET.

But I see a big problem, with TARGET defined correctly gcc can't be
built, the error message says "there is no support for DWARF2 exception
handling with a 64-bit Windows target".  Perhaps you have uncommitted
changes (enabling sjlj exception handling).

sjlj exceptions are enabled for the mingw-w64 toolchain:

I'll update the comment as neither of these are mentioned.

Cheers,
