I didn't know that Solaris had such a file, but when I looked closer
at our new Solaris 10 system I actually found one:

  $ ls -l /proc/self/path/a.out
  lrwxrwxrwx   1 gisle    other          0 Jan 30 04:01 /proc/self/path/a.out -> /usr/bin/ls

Configure does not seem to probe for this one.  Is this one useable?

Earlier we have tried to extract this path from /proc/self/auxv, but
that didn't quite work out:
