[RS6000] linux startfile/endfile

These need to match the gnu-user.h definitions to support
--enable-default-pie.  Otherwise we end up linking the wrong startup
files when defaulting to PIE.

PR driver/81523: Make -static override -pie

-static and -pie together behave differently depending on whether GCC is
configured with --enable-default-pie.  On x86, "-static -pie" fails to
create executable when --enable-default-pie isn't used, but creates a
static executable when --enable-default-pie is used.  This patch makes
-static completely override -pie to create a static executable, regardless
if --enable-default-pie is used to configure GCC.
