Thank you very much!
You were absolutely right, adding these commits (and http://git.musl-libc.org/cgit/musl/commit/?id=0e10f740069c2d805d3199a8079b73e828c7d8d9) added defines to mmap including MAP_LOCKED which mtd needed to compile. Didn't thought on checking git for that (as I didn't know that mmap is comming from there too).
So thank you Rich, seems as you don't have to find somebody to add them anymore ;-).

Also I have to say I'm getting really great support on your mailing list, thats very nice.
