[Bug 1270862] [NEW] libpcre3 1:8.31-2ubuntu2 : not ready for --enable-jit option

[Tony Reix]

Public bug reported:

Version 8.31 of libpcre3 (pcre3 sources) is not ready for --enable-jit
option on Linux/PPC64 LE. It even does not compile.

Version 8.34 of libpcre3 does include code for Linux on PPC64-LE. However, this code still fails for JIT. It is being fixed now.
Staty tune with:  http://bugs.exim.org/show_bug.cgi?id=1430 .

The current version 8.31 of libpcre3 on Ybuntu PPC64/LE should be
replaced by the version (8.35 ?) that fixes the JIT issues on PPC64/LE
(it is OK on PPC64/BE).
