DJGPP had the same problem.  What I ended up doing was this:

ifeq ($(LIBGCCA),)
LIBGCCA := $(shell $(CROSS_GCC) -print-file-name=libgcc.a)
LIBGCCA := $(subst \,/,$(LIBGCCA))
export LIBGCCA
endif

This also reduced the number of times gcc had to be called during a
build, but relies on GNU make, which I don't think we can do for
cygwin (might be cross-built from a gmake-less machine).
