Subject: [PATCH] Bring powerpcspe STARTFILE_LINUX_SPEC up to date with the
 newer PIE_SPEC decision tree from reference GNU_USER_TARGET_STARTFILE_SPEC.
 Bring powerpcspe ENDFILE_LINUX_SPEC up to date with the newer PIE_SPEC
 decision tree from reference GNU_USER_TARGET_STARTFILE_SPEC.

Fixes issue where the incorrect start/end crti files are chosen when gcc is compiled with --enable-default-pie.
