I'm about to install a patch that introduces significant changes to the
GCC driver and a large number of tests that covers some of the above.

Its main focus was to check that aux outputs got named as per the
changes introduced in the patch, but I added some baseline tests that
would cover some of the above.

Feel free to extend gcc/testsuite/gcc.misc-tests/outputs.exp to cover
other such baseline cases you may think of.
