Subject: [PATCH 5/4] x86, asm: Fix another binutils 2.16 issue

While testing the patchset at

http://lkml.kernel.org/r/1306873314-32523-1-git-send-email-bp@alien8.de

with binutils 2.16.1 from hell, kernel build fails with the following
error:

arch/x86/ia32/ia32entry.S: Assembler messages:
arch/x86/ia32/ia32entry.S:139: Error: too many positional arguments
make[2]: *** [arch/x86/ia32/ia32entry.o] Error 1
make[1]: *** [arch/x86/ia32] Error 2
make[1]: *** Waiting for unfinished jobs....
make: *** [arch/x86] Error 2
make: *** Waiting for unfinished jobs....

due to spaces between the operators of the __USER32_CS define. Fix it so
that gas 2.16 can swallow it too.
