Description:
Mismatch between --configdir=. and DataDir, looks like the ndb_mgmd put the config.bin in
DataDir since that is current working directory.

How to repeat:
$ pwd
/home/msvensson/run

config.ini has one ndb_mgmd with DataDir=/home/msvensson/run/mgmd.1

$ ~/mysql/7.0-bug45497/storage/ndb/src/mgmsrv/ndb_mgmd --config-dir=. --ndb-nodeid=2 -f
config.ini --nodaemon --verbose

^This works fine the first time, but fails like below  next time

$ ~/mysql/7.0-bug45497/storage/ndb/src/mgmsrv/ndb_mgmd --config-dir=. --ndb-nodeid=2 -f
config.ini --nodaemon --verbose

Suggested fix:
Convert the . to a realpath
