[Bug bootstrap/19255] New: cross-chain build failure [MinGW]

[monaka at monami-software dot com]

This bug is similar to #12974.
The patch (id=5925) is fine but not enough in case the target has multilib.
It also should be added INCLUDE nearby rule stmp-multilib. Like this:

  # Build multiple copies of libgcc.a, one for each target switch.
  stmp-multilib: $(LIBGCC_DEPS)
          $(MAKE) \
            CFLAGS="$(CFLAGS) $(WARN_CFLAGS)" \
            CONFIG_H="$(CONFIG_H)" \
+           INCLUDES="$(INCLUDES)" \
            MAKEOVERRIDES= \
            -f libgcc.mk all
          $(STAMP) stmp-multilib
