Thanks for your help Matthew,

I was able, with your adivces, to build libgcc.a and also libc.a.

But some symbols are missing and I need to work more on this.

I also spent some time to rebase my work on top of
https://github.com/netbsd/src

It's there: https://github.com/fallen/NetBSD (I forked the repo)

But here is one I don't understand that I got on the freshly rebased
port, some build system understanding issue I guess:

dependall-paxctl ===> .
dependall ===> paxctl

I've read a few Makefiles around without understanding why it is missing.

Any idea?
