Fix many build errors (at least 18 build error reports) for uml on i386
by adding 2 more library object files. All missing symbols are
either cmpxchg8b_emu or atomic*386.
Here are a few examples of the build errors that are eliminated:
/usr/bin/ld: core.c:(.text+0xd83): undefined reference to `cmpxchg8b_emu'
/usr/bin/ld: core.c:(.text+0x2bb2): undefined reference to `atomic64_add_386'
/usr/bin/ld: core.c:(.text+0x2c5d): undefined reference to `atomic64_xchg_386'
syscall.c:(.text+0x2f49): undefined reference to `atomic64_set_386'
/usr/bin/ld: syscall.c:(.text+0x2f54): undefined reference to `atomic64_set_386'
syscall.c:(.text+0x33a4): undefined reference to `atomic64_inc_386'
/usr/bin/ld: syscall.c:(.text+0x33ac): undefined reference to `atomic64_inc_386'
/usr/bin/ld: net/ipv4/inet_timewait_sock.o: in function `inet_twsk_alloc':

My UML on i386 build environment is br0ken so this is not tested other
than to see that the .o files are built as expected.
If someone can test/verify it, please respond. Thanks.

Hi,
Instead of trying to build this on x86_64, I powered up my 32-bit x86
laptop and verified that this patch fixes the build errors of
undefined references to cmpxchg8b_emu() and atomic64_*_386() functions.
There are still some build errors in 2 object files:

I don't know what to do about these or what is causing them (other than
"alternatives").

I don't know what to do about these or what is causing them (other than
"alternatives").

Hi,
Instead of trying to build this on x86_64, I powered up my 32-bit x86
laptop and verified that this patch fixes the build errors of
undefined references to cmpxchg8b_emu() and atomic64_*_386() functions.
There are still some build errors in 2 object files:

I have a patch in the queue which should fix these - it "steals" the
bug/feature definitions from the x86 tree.
