    Makefile.introspection: add support for gir_LDFLAGS
    
    This allows specifying LDFLAGS for the introspection scanner.
    
    LDFLAGS are currently just appended to the CFLAGS as the current scanner
    doesn't make the difference between both, but it looked wrong to include
    LDFLAGS in the middle of CFLAGS for g-ir-scanner.
