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.

According to upstream (keithw/mosh issue #650), it's okay to have the
"locale" system command fail with "command not found" because this is a
non-critical action that occurs just before Mosh exits with an error
anyway. Thus, this patch is unnecssary, and can be removed.

Adding mosh, the mobile shell. Mosh uses ssh or dropbear as an initial
transport to start mosh-server which uses UDP to communicate with the
client. Supports a predictive model to enhance performance on weak
connections and compensate for general lag. Also supports
disconnections and reconnections seamlessly.
[Thomas:
- Add missing dependency on host-pkgconf, as noticed by Yann
E. Morin.
- Indicate that openssh/dropbear is a runtime dependency.
- Pass some variables in the configure environment to tell that SSP
support is not available when it isn't. Otherwise, it misdetects
the SSP support as being available, causing a build failure.]
