mysql_install_db "Could not find ./bin/my_print_defaults"

a default compiled mariadb (CMAKE_INSTALL_PREFIX:PATH=/usr/local/mysql) installed, with make install.

path set:

$ export PATH=$PATH:/usr/local/mysql/bin:/usr/local/mysql/scripts

$ mysql_install_db --defaults-file=~/my.cnf --datadir=~/data2

FATAL ERROR: Could not find ./bin/my_print_defaults

A work around is to include `--basedir=/usr/local/mysql` in the mysql_install_db options however this should be default on an install.

Recently changed in all versions (though problem probably existed before hand).
