[debian-mysql] Bug#844275: Bug#844275: mysql_config injects build flags which breaks the build for other packages

[Lars Tangvald]

Hi,

We've had a fix for this prepared for some time now, but haven't been 
able to find anyone to sponsor an upload to unstable. Do you know anyone 
who might be able to help?
It's ready to go from the mysql-5.7/debian/master branch at 
https://anonscm.debian.org/cgit/pkg-mysql/mysql.git
