Yes, that's right.  Well, more specifically:
 - I create a file for each CPU supported, ideally - there may be
multiple variants of this for different OS targets, and I haven't
checked any besides Linux, but I don't think there should be...

 - I create a new file, broken out of the monstrous linux target file,
for each supported linux target.

There is little common Unix support code, but there looks as if there
should be more.  After some more factoring of architecture-specific
bits, perhaps there will be.
