Rewrite the post linker in librcd/C - decrease build time with 50%+

[hnsl]

The post linker is currently a major time stealer when building. It's written in python to make use of an ELF/Dwarf library that doesn't suck (pyelftools). Unfortunately it's slow, even with pypy due to the large number of dynamic objects it needs to create. I belive that it would be much faster to have this written in C instead. The major obstacle is finding a simple elf manipulation and dwarf parsing library.

As I recall pyelftools was also a bit of a pain to set up on Ubuntu, with pypy/cpython path conflicts (I don't remember the details). This might alleviate that.

Haha, kanske kunde vara ett jobb för mig!
