[libc] Remove trivial .h.def files #149466

frobtech · 2025-07-18T07:06:15Z

Remove all the .h.def files that already express nothing
whatsoever not already expressed in YAML. Clean up a few YAML
files without materially changing any generated header output.

Many more .h.def files remain that need a bit of conversion in
YAML to express macro requirements and such.

Changes

Remove all the .h.def files that already express nothing
whatsoever not already expressed in YAML. Clean up a few YAML
files without materially changing any generated header output.

Many more .h.def files remain that need a bit of conversion in
YAML to express macro requirements and such.
