cc5ca5ce51 Extend the i386 gas testsuite to do some tests for intel_syntax. Fix all 
the errors exposed by this addition.  These were intel mode
"fi... word ptr", "fi... dword ptr", "jmp Imm seg, Imm offset", "out dx,al".
The failure with intel "out dx,al" was also present in att "out al,dx".
Extend testsuite to catch this case too.

f6af82bd44 This lot mainly cleans up `comparison between signed and unsigned' gcc 
warnings.  One usused var, and a macro parenthesis fix too.  Also check
input sections are elf when doing gc in elflink.h.

4c63da97a7 This set of patches add support for aout emulation on the x86 
assembler.  ie. You will be able to do "as --em=i386aout" on an x86
linux-elf assembler to generate aout format object files, rather than
using a separate assembler.  The aout emulation is enabled by giving
"--enable-targets=i386-linuxaout" to configure.
Oh yeah, there's a couple of fixes too.  Error messages shouldn't be
passed to printf in the format arg just in case someone puts a `%' in
the message.
