Log Message:
The configure.in/aclocal.m4/configure shipped with xcdroast source
accidently included a check for PCRE.

xcdroast build and installed software does not use pcre.

This patch-ab removes the configure check for pcre.

And the dependency for pcre is removed and package revision is bumped.

This patch is same as if patched using new configure found via
http://www.xcdroast.org/xcdr098/patches/ (and that webpage has five
other patches to consider).

This was okayed by maintainer, Thorsten F.
