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

commit 3b62d74b6a33a7c71c104d1b3e414044a5978cd5

    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().
