40508bb424 linux-user: change do_semop to return target errno when unsuccessful
do_semop() is called from two places, and one of these fails to convert
return error to target errno when semop fails. This patch changes the
function to always return target errno in case of an unsuccessful call.

a540f158db configure/Make: Build libfdt from submodule DTC
Configure to use the DTC submodule to build libfdt when no system libfdt
is found. Prompt to install the DTC submodule if --enable-fdt is set but
no DTC can be found.

DTC has no out-of-tree build capability, so the configure will symlink
the Makefile and scripts directory in the out of tree build directory
and pass in all the needed DTC arguments to make out of tree build happen.
Ideally we fix the DTC make to support out of tree, but did it this way to
avoid commits to DTC.

This test compares all of the default register values against the

places are really only visible to the BIOS though which is why
this hasn't created any problems.

The deviation actually happens in the core PCI layer so I suspect
it's not a simple fix if we really care to fix it.  For now, just
disable the affected checks.

acbbc03661 rng random backend: check for -EAGAIN errors on read
Not handling EAGAIN triggers the assert

qemu/backends/rng-random.c:44:entropy_available: assertion failed: (len != -1)
Aborted (core dumped)

This happens when starting a guest with '-device virtio-rng-pci',
issuing a 'cat /dev/hwrng' in the guest, while also doing 'cat
/dev/random' on the host.
