Several architectures define ARCH_DLINFO to [sometimes] contain
NEW_AUX_ENT entries, but don't define AT_VECTOR_SIZE_ARCH with the
corresponding maximum number of NEW_AUX_ENT entries.

In practice this doesn't cause any problems as AT_VECTOR_SIZE_BASE
includes space for AT_BASE_PLATFORM which none of these arches use, but
nevertheless lets define it now and add the comment above ARCH_DLINFO as
found in several other architectures to remind future modifiers of
ARCH_DLINFO to keep AT_VECTOR_SIZE_ARCH up to date.

Arch maintainers, please take via your own trees if you're happy to do
so.

- I haven't included an update for x86/um as it doesn't follow the same
  pattern as other architectures so it is unclear to me whether it has
  the same issue.

- Build tested on MIPS, ARM & tile.

- Tested on MIPS.
