[Buildroot] [git commit master 1/1] external toolchain: Only prefix path if specified

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=5d6ff452add2d4e902409ed35accfa59adba37f2
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Only prefix the external toolchain calls with its absolute path if
BR2_TOOLCHAIN_EXTERNAL_PATH is set, otherwise just assume it will
be available in the path.
