still did not get to the bottom of this, but all these libarchive deps
comes from libarchive.la :
# Libraries that this one depends upon.
dependency_libs=' -lacl -lattr -lexpat -llzma -lbz2 -lz -lcrypto'

This is needed for a static build of pacman, but an alternative is to
use pkg-config --static --libs libarchive somewhere in the Makefile,
which gives the same dep list.

Anyway, removing the .la file 'fixes' the problem, but well ...
