Freetz toolchain changes gcc's default from --no-as-needed to --as-needed.

uClibc Makefile however relies on --no-as-needed being the default (to be more precise the linking order is not correct everywhere).
Instead of fixing the linking order (requires more effort) add an explicit --no-as-needed to fix the problem.
