This fixes a SIGSEGV error on qemu exit.

Here is the valgrind output related to this error

==3648== Process terminating with default action of signal 11 (SIGSEGV)
==3648==  Access not within mapped region at address 0x8
==3648==    at 0x40636B: host_alarm_handler (vl.c:1345)
==3648==    by 0x52D807F: (within /lib/libpthread-2.9.so)
==3648==    by 0x5C0A12E: tcsetattr (in /lib/libc-2.9.so)
==3648==    by 0x4DD601: term_exit (qemu-char.c:700)
==3648==    by 0x5B636EC: exit (in /lib/libc-2.9.so)
==3648==    by 0x5B4B5AC: (below main) (in /lib/libc-2.9.so)

This simple fix check for a valid pointer as host_alarm_handler is
also called after alarm_timer is released in the exit path.

This text is no longer accurate. After the patch is applied, the
generated version at http://www.nongnu.org/qemu/qemu-doc.html should be
regenerated.

This patch is also a candidate for the stable branch. (The URL above is
probably generated from the stable branch anyways, so maybe it goes
without saying.)

The only target dependency for most hardware is sizeof(target_phys_addr_t).
Build these files into a convenience library, and use that instead of
building for every target.

Remove and poison various target specific macros to avoid bogus target
dependencies creeping back in.

Big/Little endian is not handled because devices should not know or care
about this to start with.

ARMv7 defines a new behavior for ARM data processing instructions
compared to earlier architecture revisions; when the destination
register is R15, a Branch and Exchange operation is executed rather
than a simple Branch to the target address. This patch corrects the

applied after applying the previous patch in this patch set.

Now that we're using enums for module types, it makes no sense to bother keeping
a list of module types when we know exactly how many they are.

Switching to an array simplifies the code and eliminates the aforementioned bug.
