Commit Message

Ross Burton Feb. 27, 2019, 6:33 p.m. UTC 
PCRE has an optional JIT for performance.

Add a PACKAGECONFIG for this, enabled by default.

Also add a patch so that auto-detection of JIT availablity, which is required to
enable the JIT by default, works with out-of-tree builds.

+In out-of-tree builds the #include fails because $srcdir isn't in the include path.  Set CPPFLAGS so that it is.
