DESTDIR install fails when fast-install not supported (HP-UX/PA, IRIX)

[Ralf Wildenhues]

OK for HEAD, to turn the destdir tests into expected failures on
HP-UX/PA (due to hardcode_action=relink) and IRIX 6.5 (due to
inherit_rpath=yes), and document the current situation of DESTDIR
installs?

Cheers,
Ralf

        * tests/destdir.at: XFAIL if `fast_install' is no.
