Subject: Makefile: refactor generators to be PWD-independent

We have multiple scripts that generate headers from other data. All of
these scripts have the assumption built-in that they are executed in the
current source directory, which makes them a bit unwieldy to use during
out-of-tree builds.

Refactor them to instead take the source directory as well as the output
file as arguments.
