I haven't tried it but this should work on platforms with traditional
UNIX ld semantics. The first "-lgssapi" resolves GSSAPI references in
the application, then the mech libs resolve the mech initialization
calls inside libgssapi, then the second "-lgssapi" resolves GSSAPI
references inside the mech implementations.

Platforms with more advanced linker semantics (AIX comes to mind) do not
need the second "-lgssapi" because they can search the same archive
multiple times for missing symbols.
