Remove a feeble attempt at providing ABI compatibility for the C++ portion
of the PCRE library. Relying on the C++ compiler to crunch symbols in a
particular way is platform dependent at best, and the comments indicate
that this was done for OSX.
Also, the test misfired on SunOS leading to breakage (PR pkg/38768).
