[PATCH 1/2] libpcre: recipe cleanup

[Ross Burton <ross.burton@intel.com>]

The following options are the defaults, so remove them:
--enable-newline-is-lf
--with-match-size=2
--with-match-limit=10000000

We don't appear to need to pass -D_REENTRANT anymore (added with no explanation
to oe-classic in 2006).

Explicitly adding -lstdc++ doesn't appear to be required anymore (added for
PowerPC in 2008).

This recipe has always rebuilt the character tables but back in PCRE 4.4 (first
added to OE) a copy of the tables wasn't distributed with the tarball so this
was required.  Since 2007 the tarball includes the tables for ASCII and
regeneration is only required if we wish to use EBCDIC, which we do not. Drop
the patch adding CC_FOR_BUILD support and remove --enable-rebuild-chartables
