Create global is_static() to eliminate from the library init function.

Create global is_static() to eliminate from the library init function.

Very simple / crude method of removing 'is_static' from initialization.
Why should we require an application tell us whether it is linked
statically or dynamically to libLVM?  If the application is linked
statically, but libraries exist and dlopen() calls succeed, why
do we care if it's statically linked?
