 That is really weird, the toolchain-external-custom dependencies should be
defined no matter what... Could you pastebin the output make 'make -qp' somewhere?

 I would think it would be somehow related to gcc not being executable, but
since this occurs before the package is even extracted... Just to be sure, what
is the contents of output/build when you get this error? There is no
toolchain-external-custom directory yet, right?
