If you followed that guide, look at that "helpful" make file:

cross-gcc: cross-binutils cross-gcc-first cross-newlib gcc-$(GCC_VERSION)-$(CS_BASE) multilibbash 
    mkdir -p build/gcc-final && cd build/gcc-final && \
    mkdir -p $(PREFIX)/$(TARGET)/usr/include && \
    ../../gcc-$(GCC_VERSION)-$(CS_BASE)/configure            \
    --prefix=$(PREFIX) --with-pkgversion=$(PKG_VERSION)        \
    --with-bugurl=$(BUG_URL) --target=$(TARGET) $(DEPENDENCIES)    \
    --enable-languages="c,c++" --with-gnu-ld --with-gnu-as        \
    --with-newlib --disable-nls --disable-libssp            \
    --disable-shared --enable-threads --with-headers=yes        \
    --disable-libmudflap --disable-libgomp     --enable-lto        \
    --disable-libstdcxx-pch    --enable-poison-system-directories     \
    --with-sysroot="$(PREFIX)/$(TARGET)"                \
    --with-build-time-tools="$(PREFIX)/$(TARGET)/bin"        \
    --enable-extra-sgxxlite-multilibs $(CS_SPECS) && \
    $(MAKE) -j$(PROCS) && \
    $(MAKE) installdirs install-target && \
    $(MAKE) install-gcc

Does that, or does that not say: --with-newlib?

Translation: "newlib" means it is a "standalone" compiler, not a "hosted" compiler for code hosted by an operating system.

Perhaps the description here is clearer:
http://knetconnect.com/KeK/KeK_refer...bsection-B.1.2

Translation:
Change your makefile to build a (e)glibc based compiler not a newlib based compiler.

Note: There are ways to build "hosted" code with a "standalone" compiler but that is far too complicated when you can just build what you need.

Or:
You might want to try crosstool-ng - - I am pretty sure it will run on Mac, check the documentation on their home page.

Or:
Do your builds in Linux VM on your Mac - then you can just use the posted binary tool chains.
