gcc-3.2: gcc driver doesn't pick up crt0.a from /usr/lib

This is a followup to my "gcc-3.2: gcc driver doesn't pick up crt0.a
from /usr/lib" message.
I have found that configure sets GCC_FOR_TARGET to the cross-compiler I
use in the root Makefile.
GCC_FOR_TARGET = i686-pc-cygwin-gcc
Then gcc/Makefile is using it to create the spec file
specs: xgcc$(exeext)
$(GCC_FOR_TARGET) -dumpspecs > tmp-specs
mv tmp-specs specs
and obviously the spec file defines:
*cross_compile:
1
which makes gcc drop /lib and /usr/lib from the 'libraries:' search path.
IMO this is wrong considering that the configure line was:
"$r/src/$gcc/configure" --build=i686-pc-linux-gnu \
--host=i686-pc-cygwin --target=i686-pc-cygwin \
--prefix=/usr --includedir=/nonexistent/include \
--enable-languages=c,c++ \
--enable-threads=posix \
--with-system-zlib \
--enable-nls \
--without-included-gettext \
--disable-version-specific-runtime-libs \
--enable-shared \
--enable-haifa \
--enable-interpreter
Can someone shed some light here? Why GCC_FOR_TARGET is not left as
defined in the gcc/Makefile?
GCC_FOR_TARGET = ./xgcc -B./ -B$(build_tooldir)/bin/ -isystem
$(build_tooldir)/include -isystem $(build_tooldir)/sys-include
TIA,
