Subject: [PATCH] libassuan: add pkgconfig support

Upstream-Status: Denied
Signed-off-by: Chen Qi <Qi.Chen@windriver.com>
Signed-off-by: Constantin Musca <constantinx.musca@intel.com>

forward ported to 2.4.4
Signed-off-by: Armin Kuster <akuster@mvista.com>

Refactor to apply on top of 3.0.1, including reformatting as an mbox for
easier use.

Signed-off-by: Trevor Gamblin <tgamblin@baylibre.com>

Remove $prefix/bin (/usr/bin) from search path to avoid executing gpgrt-config
installed on the build system. At the very least it leads to warnings
about mis-matched architectures in the config logs.
