binutils 2.11 sh-rtems/sh-elf dies building gcc

[Joel Sherrill]

Got a test case. :)  The produced as is so bad, it can't 
handle the autoconf test code for "does compiler work". :(

When compiling this file with gcc 2.95.2:

main(){}

using the command sh-rtems-gcc -O4 -S j.c, you get this assembly code:


	.file	"j.c"
	.data
gcc2_compiled.:
___gnu_compiled_c:
	.text
	.align 2
	.global	_main
_main:
	mov.l	r14,@-r15
	mov.l	L3,r1
	sts.l	pr,@-r15
	jsr	@r1
	mov	r15,r14
	mov	r14,r15
	lds.l	@r15+,pr
	rts	
	mov.l	@r15+,r14
L4:
	.align 2
L3:
	.long	___main


which when assembled using the command "sh-rtems-as j.S" produces this
message:

j.s: Assembler messages:
j.s:21: Error: Cannot represent relocation type BFD_RELOC_32
j.s:21: Internal error!
Assertion failure in tc_gen_reloc at
../../binutils-2.11/gas/config/tc-sh.c line 3335.
Please report this bug.

Line 21 is the ".long ___main"

[If you don't include the -O4, it still fails -- the assembly file is
just longer.]

Thanks.
