fix our Makefile for pari

Pari's configure script is needlessly confusing, since it's almost impossible

search for the directory containing the file pari.cfg, hoping it's unique.

fix our implementation of "operator new"

Instead of mapping it to GC_MALLOC, map it to GC_MALLOC_UNCOLLECTABLE.
This way, if a 3rd party library puts a pointer obtained with "operator new"
into a memory area obtained with "malloc", the memory won't be collected
automatically as garbage.
