/sys$common/syshlp/helplib.hlb LINK, Qualifiers, /NATIVE_ONLY  *Conan The Librarian (sorry for the slow response - running on an old VAX)

       /NATIVE_ONLY (default)
       /NONATIVE_ONLY

    For Alpha linking, prevents the linker from passing along
    procedure signature block (PSB) information in special fix-ups
    to the image activator. The image activator uses this information
    to build jackets so that native OpenVMS Alpha images can call
    translated OpenVMS VAX images. Note that this qualifier does not
    prevent incoming calls from translated OpenVMS VAX images.
