Peter Simons d095fbb13e pkgs/development/libraries/pcre: fixed build on Darwin
The gcc version used on Darwin crashes while compiling the C++ interface
of PCRE. Building that code with -O0 avoids the crash.

longDescription = ''
The PCRE library is a set of functions that implement regular
expression pattern matching using the same syntax and semantics as
Perl 5. PCRE has its own native API, as well as a set of wrapper
functions that correspond to the POSIX regular expression API. The
PCRE library is free, even for building proprietary software.
