@py-llvmlite: this version only supports llvm 20

Build the necessary parts of llvm 20 in-place, according to
upstream instructions.

Bump PKGREVISION.

@# $NetBSD$

# This Makefile fragment is intended for those times when py-llvmlite
# doesn't support the current pkgsrc llvm version.

# Statically linking in a purpose-built LLVM as upstream urges to do.
# They support only a certain version of LLVM per release, and that
# with patches.
