These versions of GCC require insane (>2GB) amounts of memory to compile
translate.o.  As a countermeasure, disable the culprit optimization pass.
This should fix the buildbot failure for default_x86_64_fedora16.  Anyway
this is a good thing to do because people will try to compile 1.3 with
less than 2GB of memory and complain.

Commit 32761257 enabled
qemu_ld/st optimization unconditionally for some hosts.

The TCG interpreter still does not support this kind of
optimization. Therefore builds with TCI fail with an
unresolved symbol tcg_out_tb_finalize. This is fixed here.

gcc will silently accept unrecognized -Wno-wombat warning suppression
options (it only mentions them if it has to print a compiler warning
for some other reason). Since we already run a check for whether gcc
recognizes the warning options we use, we can easily make this use
the positive sense of the option when checking for support for the
suppression option. This doesn't have any effect except that it avoids
gcc emitting extra messages about unrecognized command line options
when it is printing other warning messages.

Disable clang's initializer-overrides warnings, as QEMU makes significant
use of the pattern of initializing an array with a range-based default
entry like
    [0 ... 0x1ff] = { GPIO_NONE, 0 }
followed by specific entries which override that default, and clang
would otherwise warn "initializer overrides prior initialization of
this subobject" when it encountered the specific entry.

With the next qemu version (1.3) we are going to bump the qxl device
revision to 4.  The new features available require a recent spice-server
version, so raise up the bar.  Otherwise we would end up with different

would be a major PITA when it comes to compat properties.

The usbredir 0.5 release introduced the new API for 64 bit packet ids, but
it kept the libusbredirparser.pc name as is, meaning that older versions of
qemu will still have their pkg-config check for usbredirparser fulfilled,
and build with the usb-redir device. Due to the API change there will be
some compiler warnings, but the build will succeed, however the usb-redir
device will be broken on 32 bit machines.

To solve this a new usbredir-0.5.2 release is coming, which renames the
libusbredirparser.pc file to libusbredirparser-0.5.pc, so that it will no
longer fulfill the pkg-config check of the qemu-1.2 and older releases,
stopping the (silent) breakage. This patch adjusts qemu master's configure
to properly detect the new usbredir release.

Changes in v2:
-Not only use the new .pc name in the check but also when getting cflags
 and libs!
