pari: update to 2.15.2.

Browse source 
Also:
 - use -flto=auto for multithreaded link
 - change build so we don't need to patch makefile
 - ship pdf documentation in addtion to dvi
 - use SOURCE_DATE_EPOCH for dvi files
 - backport fix for pari bug 2441

Revert "x86 (32bit): force -mpc64 on compilers that supports it."
This reverts commit ca61b6391cf95ac8af15669236e2ec5839d2ad91.
This causes problems with floating point precision on i686:
```
$ cat exp40.c
#include <math.h>
#include <stdio.h>
int main() {
volatile int a=40; /* do not optimize away the call to exp(a) */
printf("%f\n", exp(a));
}
$ cc -Wall exp40.c -lm && ./a.out
235385266837020000.000000
$ cc -Wall exp40.c -lm -mpc64 && ./a.out
235385266837020448.000000
```
Note that when pari is built using -mpc64, just *linking* with -lpari
causes the problem!!!
```
$ cc -Wall exp40.c -lm -lpari && ./a.out
235385266837020448.000000

Add targets to main makefile:
- gp-dyn
- gp-sta
- lib-dyn
- lib-sta
- install-lib-dyn
- install-bin-dyn
Also: define a .NOTPARALLEL target so that top targets are not run in parallel.
Otherwise, running several targets with -j is broken.
Examples:
1. "make -j8 gp lib-sta lib-dyn" fails once in a while
2. "make -j8 doc docpdf" fails every time
With .NOTPARALLEL, both seem to work reliably.
