Currently when using the change command to switch the file in the cd drive
the command doesn't complain if the file doesn't exit or can't be opened
and the drive keeps the existing image. This patch adds a qerror_report
call to print a message out indicating the failure. This error message
can be used to catch failures.
Current behavior:

Register fp (frame pointer) is a bad choice for compilations
without optimisation, because the compiler makes heavy use
of this register (so the resulting code crashes).
Register s0 had been used for TCG_AREG1 in earlier releases,
but was no longer used and is now free for TCG_AREG0.
The resulting code works for compilations without
optimisation (tested with qemu mips in qemu mips
on x86 host).

Using $pkgconfig instead of pkg-config will use
${cross_prefix}pkg-config if that is available.
This fix is needed for cross compilations without
modified PATH. Without the fix, PATH must be modified
to find the cross pkg-config before the native
pkg-config.

Since commit 8da3ff1809 ("MMIO callback
interface changes"), the addresses passed to the I/O functions are an
offset to the start of the area. As a consequence, there is no need to
correct the address using the value of IOBR. This make possible the use
of the default MMIO functions. Moreover the addresses are now remaped
when the value if IOBR change.
The memory area corresponds to the devices behing the PCI bus, it should
not be mapped by the PCI controller. Remove the corresponding code.

Recovery of branch condition in the exception handling
code was not converted to TCG. Because the condition
