ld(1) is selective on when/how it calls conv_check_native() to provide
the correct relocatable object class processing.

Most other sgs utilities simply call conv_check_native() at startup,
and thus get an isaexec effect.  The LD_NOEXEC_64 is a freebie that's
embedded in conv_check_native() - admittedly this was originally
designed for ld(1)'s use.
