Add support for memstick generation on PowerPC. This is a little suboptimal
since glabel doesn't know about APM partitioning yet, but works well enough.

# This script generates a "memstick image" (image that can be copied to a
|
||||
# USB memory stick) from a directory tree. Note that the script does not
|
||||
# clean up after itself very well for error conditions on purpose so the
|
||||
# problem can be diagnosed (full filesystem most likely but ...).
