I saw that, but toybox is designed to build the same way the kernel does, I.E.
one CROSS_COMPILE=prefix- rather than specifying each individual tool.
And it works now with the NDK if you add that symlink. :)

I added another portability.h stanza and I _think_ that covers everything except
the llvm-cc symlink. It still errors about strip not understanding -o but
automatically falls back to copying the unstripped version to the output, and is
thus at least testable.
(And hey, my netbook dying means the machine I'm running it on now has the
x86-64 instruction that was missing in the startup code, so I don't need to run
it under qemu-x86_64 anymore. :)
