Log Message:
Drop support for svr4 on i386. This feature is not maintained, not
reliable, and of a limited use case. Most svr4 applications got time to be
ported to linux, and we do have a functional, maintained linux emulation.

Reduces the number of entry points into the kernel, the number of
places that need special care (cpu context).

Note that compat_svr4 is still available on sparc.
