I am seeking for help with awkward issue with libtool while building this library: http://github.com/mspanc/vspec
When i build it on my ubuntu 14.04 box, it works fine, add during make install it creates appropriate .so.VERSION_INFO symlinks.
However, when I try to cross compile it using Cerbero build system from GStreamer project (http://cgit.freedesktop.org/gstreamer/cerbero/), which basically bootstraps toolchains for cross-compilation, during make install it creates only .so files (no .so.VERSION_INFO symlinks), but only for this library, it makes this succesfully for other libs within the same build environment.
Apparently, there must be some difference, but I diff automakes of vspec and other project that installs fine for quite some time already and still can't figure out what's the root cause of the problem.
I have found out that libtool script in the broken library generated while running ./configure --prefix /root/cerbero/dist/android_armv7 --libdir /root/cerbero/dist/android_armv7/lib --disable-maintainer-mode --disable-silent-rules --disable-introspection --host=arm-linux-androideabi has version_type=none while one that builds has this variable properly set to linux. That difference later causes libtool to not add symlinks.
Can anyone here give me any hint where should I seek for what causes invalid host recognition while generating libtool?
Below log from Cerbero's make install:

----------------------------------------------------------------------
Libraries have been installed in:
/usr/local/lib
If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
- add LIBDIR to the `LD_LIBRARY_PATH' environment variable
during execution
- add LIBDIR to the `LD_RUN_PATH' environment variable
during linking
- use the `-Wl,-rpath -Wl,LIBDIR' linker flag
- have your system administrator add LIBDIR to `/etc/ld.so.conf'
See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

For Android, this is expected libtool output for this platform. See comments on this libtool patch. Versioned libraries will not be added to Android.
