I have tried building using a number of the samples ("x86_64-w64-mingw32,x86_64-pc-linux-gnu" and "x86_64-unknown-linux-gnu") but I am running into build errors, as shown below. I am not building the gold linker, nor am I attempting to link statically, and I am building on a case-sensitive file system. The build.log and config are shown after the error listing.

I think MacOS X support is incomplete. For x86_64 toolchain creation
you require to provide some endian.h.
In OpenADK I use:
http://cgit.openadk.org/cgi/cgit/openadk.git/tree/adk/include
Which is included via HOST_EXTRACFLAGS:
