Optimized extracting the classes in the framework ... do not pipe through

awk, which is slow - rather use a set of sed commands

# __objc_class_name_XXX which is not 'U' (which would be a reference
# to a class implemented elsewhere), it must be a class implemented in
# this module.
#
# The 'sed' command parses a set of lines, and extracts lines starting
# with __objc_class_name_XXXX Y, where XXXX is a string of characters
# from A-Za-z_. and Y is not 'U'. It then replaces the whole line
# with XXXX, and prints the result. '-n' disables automatic printing
# for portability, so we are sure we only print what we want on all
# platforms.
