make distribution fails with call to cap_mkdb

[jdyke]

Trying to rebuild a jail and am getting an error on `make distribution`
I was able to do this when the server was at 5.3-RELEASE without error, but 
since upgrading to 5.4-RELEASE it continusiously fails.

The error is:
cap_mkdb: illegal option -- l
usage: cap_mkdb [-v] [-f outfile] file [file ...]

which seems to originate from the command:
cap_mkdb -l /slaves/jail/master/etc/login.conf

Did this command ever or recently take a -l option?

Could this be a bug in make?

Thanks for any assistance/guidance.
