build: skip toolchain detection for some targets
Most developers run the `clean`, `checkpatch` and other similar targets without specifying any other additional build options. When combined with a flow where the developer passes `CROSS_COMPILE` or `CC` explicitly, and where the default-configured tools are not on the PATH, these targets will warn about unrecognized toolchain tools. This change is a workaround for this whereby the toolchain makefile is not expanded unless a target *not* named `*clean`, `check*` `doc` or `*tool` has been specified.
