config.sub: Systematize parsing of machine code formats

Browse Source 
Instead of treating them as OSes, we treat them as their own category.
This is modeled on what LLVM does with its `ObjectFormatType` enum [1],
advancing my long-running project of trying to nudge GNU config and LLVM
towards each other, taking the best ideas of both.

Currently, my emphasis is just on code cleanup. There are just a few
tests for newly supported changes that fall out of this. But down the
road, this also opens the door to parsing configs with more than 4
components, like [2].

* config.sub: Save machine code format name separately from the OS name.
* doc/config.sub.1: Regenerate.
* testsuite/config-sub.data (arm-unknown-none-aout,
arm-unknown-none-pe): New entries.
