zmqpp recommand at least a c++ compiler g++ >= 4.7
[1] for c++11 support and won't be backward compatible
whith older compliler for the next release (4.x)
due to harcoded -std=c++11 flag [2]
Blackfin ADI toolchains use a g++ 4.3 which use an
experimental c++11 support (c++0x) has not enough c++11
support to build zmqpp.

zmqpp needs some fairly advanced C++0x features, which apparently
aren't all available in gcc 4.5 used in PowerPC Sourcery 2011.03. So
this commit excludes both this toolchain and the older 2010.09 one.

When a package A depends on config option B and toolchain option C, then
the comment that is given when C is not fulfilled should also depend on B.
For example:
config BR2_PACKAGE_A
depends on BR2_B
depends on BR2_LARGEFILE
depends on BR2_WCHAR
comment "A needs a toolchain w/ largefile, wchar"
depends on !BR2_LARGEFILE || !BR2_WCHAR
This comment should actually be:
comment "A needs a toolchain w/ largefile, wchar"
depends on BR2_B
depends on !BR2_LARGEFILE || !BR2_WCHAR
or if possible (typically when B is a package config option declared in that
same Config.in file):
if BR2_B
comment "A needs a toolchain w/ largefile, wchar"
depends on !BR2_LARGEFILE || !BR2_WCHAR
[other config options depending on B]
endif
Otherwise, the comment would be visible even though the other dependencies
are not met.
This patch adds such missing dependencies, and changes existing such
dependencies from
depends on BR2_BASE_DEP && !BR2_TOOLCHAIN_USES_GLIBC
to
depends on BR2_BASE_DEP
depends on !BR2_TOOLCHAIN_USES_GLIBC
so that (positive) base dependencies are separate from the (negative)
toolchain dependencies. This strategy makes it easier to write such comments
(because one can simply copy the base dependency from the actual package
config option), but also avoids complex and long boolean expressions.

This patch lines up the comments in Config.in files that clarify which
toolchain options the package depends on.

Now that zeromq has been bumped to version 3.2.2, we need to provide the
C++ binding using a separate package. The zmqpp package provides a
high-level C++ wrapper library around the zeromq C API.
