Hello!

The Debian lintian package checker found a warning about a cross-compile
unsafe way to find pkg-config:
https://lintian.debian.org/tags/autotools-pkg-config-macro-not-cross-compilation-safe.html

The attached Patch 0001 fixes this by using the appropriate
PKG_PROG_PKG_CONFIG macro.

Patches 0002 and 0003 refresh aclocal.m4 to include the needed macros
from pkg.m4 and then refresh the configure script, but it is well
possible this is done at another place during the Bacula release
process. In that case those patches are of course not needed.

I have so far implemented this change in a non-releases branch of the
Debian packaging repository and test-built packages from it. My testing
so far has not revealed any negative changes.

All in all, pkg-config is only used during the building of "bat" so the
impact is low.

Grüße,
Sven.

Subject: [PATCH 1/3] Use PKG_PROG_PKG_CONFIG macro to search for pkg-config
Cc: s...@svenhartge.de

Using AC_PATH_PROG(PKGCONFIG, pkg-config, pkg-config) to search for the
pkg-config binary is not cross-compile safe, it may pick up the wrong
binary, causing libraries being used from the from path.

pkg.m4 provides the macro PKG_PROG_PKG_CONFIG to avoid this problem.

This potential problem was found by the Debian lintian package checker:
