[RFC] add gdb into the cross-build target

[Adrian Chadd]

Hi,

I'd like to propose adding gdb into the cross-build target.

This way MIPS, ARM, PPC etc targets will have gdb-<arch> built in the
cross-build environment, so it can be (hopefully) used for cross-build
debugging of the kernel, as well as remote debugging out of the box.

Here's my example patch. Thanks!




Adrian
