Solaris equivalent for getauxval(AT_EXECFN)

[Stephen Nelson-Smith]

The source of which is here
https://github.com/illumos/illumos-gate/blob/master/usr/src/cmd/ptools/pargs/pargs.c

So if you want to write your own, rather than use the built in, you
can see the implementation.

Hope that helps, and I haven't misunderstood what you're trying to do.

Happy New Year!
