pari: update to 2.15.2.

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

-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.
