toolchain.inc: Update and fix the test-toolchain target

Due to some change, the test-toolchain was no longer working, and was
always reporting that the toolchain is out of date.

This fixes the failure, and prints both the expected versions of Clang,
GCC, and IASL on failures.

Additional changes fix some indentation issues and skip trying to update
submodules when the test is run.
