[Buildroot] [PATCH 0/7 v2] Set of patches to add MariaDB galera cluster

[Sylvain Raybaud]

Add MariaDB Galera Cluster as an alternative implementation of MySQL, inside package/mysql.
Also add galera which is needed for running a cluster and check on which galera depends.
Introduce a few other modifications to busybox.config and libaio.mk necessary to make this work.

Changes v1 -> v2:
 - Fixed check Config.in (suggested by Yann E. Morin)
 - Fixed check hash file (suggested by Yann E. Morin)
 - Changed check dependency from pgkconf to host-pkgconf (suggested by Yann E. Morin)
 - Fixed check license (suggested by Yann E. Morin)
 - Leave CHECK_INSTALL_STAGING and CHECK_INSTALL_TARGET to their default values (suggested by Yann E. Morin)
 - Explain why we need to build host-libaio in commit log (suggested by Yann E. Morin)
 - Add information about the impact on busybox binary size induced by patching busybox.config (suggested by Thomas Petazzoni)
 - Change commit titles (suggested by Thomas Petazzoni)
 - Remove duplicated block in package/galera/galera.mk

Sylvain Raybaud (7):
  check: new package
  libaio: add host variant
  galera: new package
  pkg-cmake: add PKG_CONFIG_* variables to help cmake find host packages
  busybox: adjust configuration to add fancy options to the sleep applet
  mysql: move patches into a version-specific subdirectory
  mysql: add mariadb galera cluster variant
