John Baldwin c2f37b9245 Add AT_HWCAP and AT_EHDRFLAGS on all platforms.
A new 'u_long *sv_hwcap' field is added to 'struct sysentvec'.  A
process ABI can set this field to point to a value holding a mask of
architecture-specific CPU feature flags.  If an ABI does not wish to
supply AT_HWCAP to processes the field can be left as NULL.

The support code for AT_EHDRFLAGS was already present on all systems,
just the #define was not present.  This is a step towards unifying the
AT_* constants across platforms.
