Bug#985924: pmacct FTCBFS: fails finding mysql

[Helmut Grohne <helmut@subdivi.de>]

Source: pmacct
Version: 1.7.6-2
Tags: patch upstream
User: debian-cross@lists.debian.org
Usertags: ftcbfs

pmacct fails to cross build from source, because it uses mysql_config
and mysql_config fundamentally cannot be made to work during cross
builds. A better solution is pkg-config and that actually works. Please
consider applying the attached patch to try pkg-config before
mysql_config. Doing so makes pmacct cross buildable.
