Share i386-linux target description between GDB and GDBserver
The code on creating i386-linux target descriptions are quite similar
between GDB and GDBserver, so this patch moves them into a shared file
arch/i386.c. I didn't name it as i386-linux.c, because I want to reuse it
to create other i386 non-linux target descriptions later.
