I have no idea why that's there for master (probably left over from the
old nm_warn/nm_error/etc calls) so I've removed it there.

I guess all we can do for 0.8.4 (since this is a public header, and we
can't really #include <config.h> there since we don't distribute it) is
try to use uclibc-specific defines to make the nm_print_backtrace() call
be a noop if we're on uclibc?
