For some reason some arches, including powerpc, use a differently named
field in mm->context for the vdso address. Fixed by:

Add runtime/autoconf-mm-context-vdso-base.c for vma.c vdso catching.
Some architectures use an unsigned long vdso_base field in mm->context,
instead of a void *vdso field. Detect either in _stp_vma_match_vdso().
