Buildroot supports an external toolchain, but it isn't easy to create one.
The easiest is to use a crosstool-NG toolchain: build it, install it in some
central place, and use it as an external toolchain from buildroot.
It would be nice if buildroot also supported creation of an external
toolchain (based on an internal toolchain config). The toolchain is currently
built in output/host/usr/... and is not relocatable, so it's difficult to
share it between different buildroot builds.
