Yes. Due to:
configure.ac:
CROSS_SYSTEM_HEADER_DIR='$(TARGET_SYSTEM_ROOT)$${sysroot_headers_suffix}$(NATIVE_SYSTEM_HEADER_DIR)'
I also saw:
config/spu/t-spu-elf:19:NATIVE_SYSTEM_HEADER_DIR = /include
There's no native spu-elf toolchain for sure, so this looks like
some precedent.

Right, that should work too, though the --with-headers pseudo-ugly
option avoided needless copies of files in the end.
I'm not sure what is the best approach. I've just built a toolchain
with the patches below. A bunch of files showed up on include-fixed,
amonst which, there was a include-fixed/syslimits.h file.
