[Buildroot] [PATCH] mysql server and client 5.1.x and 5.5.x

[Thomas Petazzoni]

Hello Heiko!

Thanks for taking care of the MySQL package. I have a few comments
below, but first, is there a good reason to support both MySQL 5.1 and
MySQL 5.5 ? Wouldn't supporting MySQL 5.5 be enough ?

Since this depends on BR2_PACKAGE_MYSQL, which already selects ncurses
and readline, do we really need those selects again ?

This patch needs a description + Signed-off-by line.

Could you detail why host-mysql is needed as a dependency ? (For
example by adding a comment).

What about using the configuration option for the data directory ?

Normally, all those definitions should be before the
AUTOTARGETS/CMAKETARGETS calls.
