Is it possible to call functions in a .a static library file? (Unix)

No you can't do that. Static library files are sometimes in a format
depending on the compiler used to create them and there is no
standardized way of linking to symbols in such a library. More
problematic there is no mechanisme to load and initialize the library in
a standardized way. So LabVIEW does not even try to do such things and
with a good reason.
What you could do is create a wrapper shared library which links to your
static library and makes its functions available in such a way.
