The removal of this file appears to have been premature; it's not a feature
enabled by Kconfig, but it's a arch-level feature regardless. Put it back
for now until some happy future time when we decide how we really want to
document such features.
This reverts commit 2bef69a385.

A number of architecture ports are obsolete and getting dropped,
so we no longer want to track the respective features.
We already removed the lines for metag and mn10300, this does
the same edits for all the others.
For the remaining 21 architectures, this shows how many are known
to implement each given feature:

need to be added.
