posix_fadvise: make posix_fadvise[64] similar on all archs
Remove all versions, that can be covered by the common one. Drop incorrectly implemented fallback support, if __NR_fadvise64_64 is not available. To support 64 bit ppc, move ppc support into common. Cleanup including headers. Signed-off-by: Peter S. Mazinger <ps.m@gmx.net> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
