RPM5 v4.4.9 contained .rej files in the tar.gz, which made patch-kernel
choke. Dirty I know ... but yea

Removed that line. it was hanging around from my previous cleanup ... :\

I do this later on....
rpm: libbeecrypt libneon libpopt ...
Problem is I don't want to depend on the fixed library names .... would
you suggest I depend on $(STAGING_DIR)/usr/lib/libbeecrypt.so ... etc?

I can try filter it out a bit, but 4.4.9 was very very picky.

Lets get rpm in without python, then improve on the extras later :)

4.4.9 was a nightmare ... I started from scratch, then added line by
line. I'll try 5.0.x and filter out.

yea ... i'm busy trying to determine if more are required

I looked in some other .mk's and saw they normally depend on the package
name?
