#
# This script tries to first build a cross-compiler, then we build
# uClibc support for it. The last step then is to build glibc,
# which may or may not work... You may give "force" as a command
# line argument to indicate that you don't need your .config files
# any longer. Otherwise than that, we're expecting to see pristine
# sources.
