Some people complain about missing libpcre.so, so better include it.

Signed-off-by: Thomas Heil <heil@terminal-consulting.de>

This adds the pcre, aka libpcre package from the old svn tree. Ive
updated the package to the last version end checked that it builds with
various plattforms. The patch 750-pcre_config_cross.patch is not longer
necessary, so I removed him.

The old package needs to be removed from the svn package tree.
