No, nothing like spec files. As I said, you want to be able to specify
that the arm-linux target uses --sysroot=/somewhere/arm-linux and that
the arm-netbsd target uses --sysroot/somewhere/arm-netbsd. That and
maybe some -B option to help finding the linker likely already covers a
good 90% of what people need for setting up cross-compilation, if the
automatic triple-based search is not enough.
