pkgs/development/libraries/pcre: fixed build on Darwin

Browse Source 
The gcc version used on Darwin fails to compile the C++ interface to the PCRE
library when optimizations are enabled. Building C++ code with -O0 remedies the
problem. This is unsatisfactory, though, because the resulting library is
likely to perform more poorly than it would if built with -O2 or -O3.
