libosmocom VERSION doesn't get set properly

hi,

when building libosmocom in osmocom-bb/src/shared (using the git-subtree script to keep everything up to date), the Makefile in src/shared/libosmocore/build-host doesn't have the version information set properly, instead i get:

PACKAGE_VERSION = UNKNOWN VERSION = UNKNOWN

this is causing problems compiling stuff that require libosmocom at a specific version, like some of the airprobe tools. i'm running mac os x 10.6.4, using autoconf 2.68, automake 1.11.1, binutils 2.20.1, gcc 4.5.1.

when building the master git branch of libosmocom outside of osmocom-bb (bootstrapping using the bootstrap script from airprobe/gsm-receiver), the version gets set properly.

thanks
