czmq: needs MMU

Fixes:
http://autobuild.buildroot.net/results/6dd/6dd6954e5ab8c422070e53b0e616e1b1a821c626/

Also, remove the Blackfin toolchain dependencies as these are redundant now
since Blackfin is a noMMU arch.

You forgot its reverse dependencies (filemq). Committed with that fixed,
thanks.

Shouldn't the option and the comment have opposite conditions?
I.E: Either display the option or the comment?

MMU is usually an attribute of the CPU architecture, and not a software 
configuration issue. In this case we don't show the software dependencies 
comment since the user can't do much about the CPU architecture of choice in 
the context of Buildroot. See 
http://buildroot.net/downloads/manual/manual.html#_literal_config_in_literal_file, 
under "Dependencies on target and toolchain options".
