powerpc: Work around ld bug in older binutils
Commit 549e8152de8039506f69c677a4546e5427aa6ae7 ("powerpc: Make the 64-bit kernel as a position-independent executable") added lines to vmlinux.lds.S to add the extra sections needed to implement a relocatable kernel. However, those lines seem to trigger a bug in older versions of GNU ld (such as 2.16.1) when building a non-relocatable kernel. Since ld 2.16.1 is still a popular choice for cross-toolchains, this adds an #ifdef to vmlinux.lds.S so the added lines are only included when building a relocatable kernel. Signed-off-by: Paul Mackerras <paulus@samba.org>
