It did, I was at least able to compile more of the code, though it still 
failed, this time due to some problem with automake. Part of the error 
states that I can pass a flag (--disable-dependency-tracking) to the 
configure script, how can I do that? This is the (as far as I can tell) 
relevant part of the build.sh output:

config.status: executing depfiles commands
config.status: error: in 
`/home/nando/Documents/Schule/Maturitaetsarbeit/neu/netbsd-src-ftp/src/tools/file/obj/build':
config.status: error: Something went wrong bootstrapping makefile fragments
    for automatic dependency tracking.  If GNU make was not used, consider
    re-running the configure script with MAKE="gmake" (or whatever is
    necessary).  You can also try re-running configure with the
    '--disable-dependency-tracking' option to at least be able to build
    the package (albeit without support for automatic dependency tracking).
See `config.log' for more details

Maybe it might be worth to note that in e.g., tools/compat/README if it 
is a common problem.
