We have code for a quite a few block formats. While I trust that all
of these formats are useful at least for some people in some
circumstances, some of them are of a kind that friends don't let
friends use in production.
This patch provides an optional block format whitelist, default off.
If a whitelist is configured with --block-drv-whitelist, QEMU proper
can use only whitelisted formats. Other programs, like qemu-img, are
not affected.
Drivers for formats off the whitelist still participate in format
probing, to ensure all programs probe exactly the same. Without that,
QEMU proper would be prone to treat images with a format off the
whitelist as raw when the image's format is probed.

You would only see this error on a fresh clone when srcdir == objdir. configure
will fail because roms/pcbios doesn't exist.
git submodule integration doesn't cleanup very well when switching between
branches so you'll get an roms/pcbios directory from normal operations if you
switch between old branches.
Thanks to a mistake in configure, if you build outside of srcdir, you'll also
get a valid roms/pcbios.

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
