Currently, building czmq statically fails for some architectures with undefined
references to the math library:
/usr/powerpc-buildroot-linux-uclibc/sysroot/usr/lib/libstdc++.a(compatibility-ldbl.o): In function `std::tr1::hash<long double>::operator()(long double) const':
compatibility-ldbl.cc:(.text._ZNKSt3tr14hashIeEclEe+0x3c): undefined reference to `frexpl'
It turns out that this is actually a problem with libstdc++. Depending on the
arch, some functions will be in compatibility-ldbl.o. If you use any of these
functions, that file will be linked in. And when that file is linked in, all
the _other_ functions, which you actually don't use, are also linked in. And
one of these functions is the template function hash<long double>::operator(),
which uses frexpl.
Requiring czmq to link with -lm is a bit weird, given that neither itself,
nor any of its dependencies really need it...
So ideally it should be fixed in libstdc++ itself. However, as upstream
accepted a patch to link with -lm, we use this patch to fix static linking.

Drop the patch that no longer applies, and has instead been done
differently by upstream.

This reverts commit aa5254f1a2.
Now that zeromq's pkg-config file is fixed, we no longer need this

Also, remove the fix in czmq.mk for static build.

Since a while, the semantic of BR2_PREFER_STATIC_LIB has been changed
from "prefer static libraries when possible" to "use only static
libraries". The former semantic didn't make much sense, since the user
had absolutely no control/idea of which package would use static
libraries, and which packages would not. Therefore, for quite some
time, we have been starting to enforce that BR2_PREFER_STATIC_LIB
should really build everything with static libraries.
As a consequence, this patch renames BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS, and adjust the Config.in option accordingly.
This also helps preparing the addition of other options to select
shared, shared+static or just static.
Note that we have verified that this commit can be reproduced by
simply doing a global rename of BR2_PREFER_STATIC_LIB to
BR2_STATIC_LIBS plus adding BR2_PREFER_STATIC_LIB to Config.in.legacy.

There is no benefit in using the shortened git revision hash. On the
contrary: the shorter the hash, the higher the risk of having collisions
with another commit.

czmq uses asciidoc for its documentation. asciidoc uses python and import
the unicodedata module, which is not in host-python. So disable asciidoc
entirely.
This doesn't get hit by the autobuilders because they don't have asciidoc
installed in their chroot.
