sparc: add -m64 when building vmlinux.lds
David Miller noticed that the build of vmlinux.lds failed to use the -m64 specifier. This caused the build to break with a bi-arch gcc with unified headers. Add the -m64 option to CPPFLAGS_vmlinux.lds so we have the correct defines available when building vmliux.lds. Signed-off-by: Sam Ravnborg <sam@ravnborg.org>
