Ok, please don't forget to send upstream.

Like this it cannot go upstream. Would upstream be interested in a patch
doing it right (E.G. using CC_FOR_BUILD)?

It is imho cleaner to unconditionally define the host mysql variables,
so the host-autotools-package macro does the right thing.

Build fails due to changes in the newest Bison, so I made porting to Bison
3.x to fix this MySQL bug:

I've applied this, but:
1/ The package lacks an init script to start the MySQL server
automatically.
2/ When mysqld_safe is started automatically, it looks for stuff
in /usr/var that doesn't exist:
700101 00:00:22 mysqld_safe Starting mysqld daemon with databases from /usr/var
/usr/bin/mysqld_safe: line 595: can't create /usr/var/buildroot.err: nonexistent directory
/usr/bin/mysqld_safe: eval: line 1: can't create /usr/var/buildroot.err: nonexistent directory
3/ Peter made some comments that have not been addressed. Since the
patch was large, I thought it would be easier to have it merged
first, and then do incremental changes.
Could you work on those changes, and submit the corresponding patches?
Thanks,
Thomas

I can fix that but we'll need to add a mysql user and I have no idea how do
it

You can to this by setting the MYSQL_USERS variable. See the example in
section 7.2.4 of the manual
(http://buildroot.net/downloads/manual/manual.html), and section 12.2 for
syntax details.
