Added patch to fix bashism

This is not a bug in dash. The following line in mk/Autoconf.mk:

    @echo -e "$(make-config-q)" > $@

is a bashism. Quoting the POSIX standard for "echo":

    "Implementations shall not support any options."

The patch I attached fixes the problem by changing it to printf, which is the portable way to do it.
