[RFU] expat-2.1.0-2

[Warren Young]

This just adds the missing .a file to the libexpat1-devel package.  The 
other file size differences are no doubt due to toolchain changes over 
the past ~10 months since I built the -1 packages.  (Upstream hasn't 
changed in that time, so I'm building from the same sources.)

Remove the -1 packages, and leave 2.0.1 as -prev.
While in the release/expat directory:

wget -e robots=off --cut-dirs=2 -np -nH -A'*2.1.0-2*' -r \
