[Buildroot] RFC: toolchain wrapper for external toolchains

This patch series adds a toolchain wrapper for external toolchains as
discussed during the Buildroot dev day after FOSDEM.

This brings two advantages:
 - External toolchains are easier to use outside of Buildroot as no
   special compiler arguments have to be used. They behave just
   like the internal toolchain.
 - The code to ensure --sysroot was used everywhere (and the workarounds
   for packages like Qt and cmake) can be removed.

It has so far been tested with Codesourcery toolchains and a number of
package combinations.
