Replacing AWK with Python in GCC?

Isn't this one of those silly problems where things are getting built on unstable foundations just because of what is there already? E.g. like initially using SATA to connect SSDs which are essentially filled with memory chips.

Surely fixing the grammar and syntax of the .opt files should be the first step, and then a trivial parser/processor could be made in any language, ideally C to ease bootstrapping.

Additionally, I've only ever found cross-compiling various Python interpreters difficult, though that was some years ago and things may have improved.
