gas: bad code: symbol as scale for indexed addressing

[John Reiser]

gas 2.11 generates bad relocatables, and gives no error message,
when a symbol is used as a scale factor on i586 under Linux.

GNU assembler 2.11
--host=i586-pc-linux-gnu --norecursion
Linux jreiser 2.2.19-6.2.1perf #1 Wed Jul 4 21:25:48 PDT 2001 i586 unknown

-----foo.s input file
foo = 8
        leal 1(%eax,%ecx,foo),%edx  # intending a scale factor of 8
-----

$ as-new -o foo.o foo.s   ### note no messages
$ echo $?   ### examine the exit code from as-new
0  ### success
$ gdb foo.o
(gdb) x/i 0
0x0:    lea    0x1(%eax,%ecx,1),%edx  ### scale factor is 1, not 8
(gdb) x/x 0
0x0:    0x0108548d   ### should be 0x01c8548d
