The native IRIX ld supports the -set_version option. In hindsight this
is obvious since the GNU linker would not use an underscore in its
option names.

@joerg: Is it possible (just as a quick local workaround) to tell
cwrappers to ignore the -set_version option including its string
argument? In the pkglint test code I found a little hint:

    CWRAPPERS_TRANSFORM.cc+= rm-optarg:-set_version
    CWRAPPERS_TRANSFORM.cc+= rm-optarg:-Wl,-set_version

The rm-optarg command is only supported by the old wrapper framework and
additionally requires that the option and its argument are merged into a
single word (see mk/wrapper/gen-transform.sh), so this doesn't work. A
variant that does work (although ugly) is:

    CWRAPPERS_TRANSFORM.cc+=        rm:-Wl,-set_version
    CWRAPPERS_TRANSFORM.cc+=        rm:-Wl,sgi1.0

Independent of any workaround, the proper solution would be to research
why GCC 8.2.0 thinks that its own ld would be the native IRIX ld.
