Eventhough it should be theoretically possible to build protobuf in
static-only, configure.ac includes an m4 macro, ACX_PTHREAD defined in
m4/acx_pthread.m4, which forcibly checks for threads *with* shared libs,
and is completely broken for static-only (as it forces -shared whatever
the user selection), ending up with these configure results:
checking for the pthreads library -lpthreads... no
checking whether pthreads work without any flags... no
checking whether pthreads work with -Kthread... no
checking whether pthreads work with -kthread... no
checking for the pthreads library -llthread... no
checking whether pthreads work with -pthread... yes
checking for joinable pthread attribute... PTHREAD_CREATE_JOINABLE
checking if more special flags are required for pthreads... no
checking whether to check for GCC pthread/shared inconsistencies... yes
checking whether -pthread is sufficient with -shared... no
checking whether -lpthread fixes that... no
checking whether -lc_r fixes that... no
configure: WARNING: Impossible to determine how to use pthreads with shared libraries
checking whether what we have so far is sufficient with -nostdlib... no
checking whether -lpthread saves the day... no
configure: WARNING: Impossible to determine how to use pthreads with shared libraries and -nostdlib
Fixing this macro is far from trivial; protobuf in a static-only
scenario is probably not too common. So, just disable protobuf for
static-only builds.

The host-protobuf package can only build on certain architectures. For
example, host-protobuf does not build on PowerPC platforms, causing
build failures on the autobuilders. Since we don't really care about
build platforms other than x86 and x86-64, this commit restricts the
build of host-protobuf to these architectures only, even though if
technically it could build on ARM and MIPS.

protobuf 2.5.0 adds an atomic operations implementation that is limited
to a few architectures only. mips64el and armeb don't work either.
