Unfortunately, creating versioned libraries requires more than just
renaming and creating a symlink.

If the library is going to be renamed during installation, then the
soname (which is set within the library when the library is linked)
needs to match a name which will exist in the target rootfs at
runtime.

In this case, since "libmvudrv.so.1.0.1" is the name which will be
present at runtime, when the build creates libmvudrv.so, it needs to
set the soname to "libmvudrv.so.1.0.1". ie add the following to the
linker commandline:

  -Wl,-soname,libmvudrv.so.1.0.1
