Robert Clausecker d8cd2d0833 depend-cleanup.sh: clean up after hash function removal from libcrypt
The hash function removal changed the mangled names of MD[45] and
SHA{256,512} hash function identifiers.  Clean these files to pick
up the symbol change.

# Our current make(1)-based approach to dependency tracking cannot cope with
# certain source tree changes, including:
# - removing source files
# - replacing generated files with files committed to the tree
# - changing file extensions (e.g. a C source file rewritten in C++)
#
# We handle those cases here in an ad-hoc fashion by looking for the known-
# bad case in the main .depend file, and if found deleting all of the related
# .depend files (including for example the lib32 version).
#
# These tests increase the build time (albeit by a small amount), so they
# should be removed once enough time has passed and it is extremely unlikely
# anyone would try a NO_CLEAN build against an object tree from before the
# related change. One year should be sufficient.
