How did you configure GMP et al? Are you really using 64-bit cygwin? And
if so, is `gcc' really the 64-bit cygwin compiler and not the default
32-bit compiler?
In any case, this looks like a general cross-compiler question that has
no obvious bearing on cygwin, so you'll probably benefit from more
expertise if you ask on a gcc or crosstool-ng [1] mailing list (the
latter seems to support several ARM variants OOTB, and is the least
painful route in my experience).
