HiPE is autoenabled on supported platforms. However, "supported"
does not mean "seems to maybe work on", it means that we regularly
test on those platforms and will fix problems if/when they occur.

x86: 386 and newer CPUs supported on Linux and Solaris 9. On Linux NPTL
glibc is preferred, or a LinuxThreads glibc configured to access thread
state via a segment register ("floating stacks"). With a non-floating
stacks glibc you must build the system without thread support if you
want HiPE support. HiPE/x86 used to work on Solaris 8, and may work on
Solaris 10, but we only have access to a Solaris 9 box for testing.
AMD64/Intel64: supported on Linux.
PowerPC: supports 32-bit user-mode processes on Linux and OSX.
ARM: supports big-endian v5 CPUs (XScale) on Linux.
SPARC: supports v9 CPUs running 32-bit user-mode on Solaris and Linux.
HiPE/x86 should work on OSX, and may work on FreeBSD, but since
we don't have those systems we won't pretend to support them.
User can still ./configure --enable-hipe if their systems do
in fact work with HiPE.
That ./configure --help doesn't list --enable-hipe is a bug; I'll
make sure that it gets fixed before R11B-2.
