Changes:
* added isa bus, hooked up to the system bus. Not sure this is correct,
but 'info pci' lists lists no pci-isa bridge in the machine ...).
* switches the default cpu to one which actually works.

Recent versions of the Linux kernel will not preempt CPU-intensive
tasks unless the clock used by sched_clock() works. On -M versatilepb
that's the 24MHz timer in the system controller. It's a very simple
timer, so implement it.

While i386, x86_64 and Sparc64/OpenBSD still worked after
df70204db5, Sparc32 and Sparc64 Linux hosts
broke.
Partially revert the commit: make the restored code conditional to
!CONFIG_USER_PIE.

Build uset targers as true PIE if user want to keep qemu
self-virtualizable.
v5:
- Split into to patches: drop link hack and add PIE support
- do not build PIE by default and drop toolchain check
v4:
- Add test for toolchain if it has proper PIE support
v3:
- One more pice of the hack was removed
- Description updated
v2:
- Add configure options do enable/disable PIE for usermode targets.
Disabling can be useful if you build uswing toolchain which has
broken PIE support. PIE for usermode targets enabled by default.

There is a link hack in linux-user which produces an executable that
looks like PIE, but always has text relocations since all object files
isn't position-independent (compiled without -fpic/-fpie). Dynamic loader
has to do more work to load a binary with text relocations.
The best way to keep this functionality is to build a true PIE without
text relocations.

We need to define _XOPEN_SOURCE and __EXTENSIONS__ macros in order to get
CMSG_ and TIOCWIN macros defined. But then _POSIX_C_SOURCE gets defined, which
is (incorrectly) used as an indicator for existence of posix_memalign() in osdep.c.

Problem: Our file sys-queue.h is a copy of the BSD file, but there are
some additions and it's not entirely compatible. Because of that, there have
been conflicts with system headers on BSD systems. Some hacks have been
introduced in the commits 15cc923584,
f40d753718,
96555a96d7 and
3990d09adf but the fixes were fragile.
Solution: Avoid the conflict entirely by renaming the functions and the
file. Revert the previous hacks.
