I'd hard-code that to "MD_MAJOR_VERSION=2". That was an ill-fated  
attempt to use the Debian changelog to drive the shared library  
versions, which IMHO is not the way to do things.

It might be in src/.libs. It really depends on the way your cross- 
compilation environment works. Something may be forcing it to not  
build shared objects.
