I've just manually tried the augmented test on Solaris 10-11.4, SPARC
and x86.  While the Solaris/SPARC assembler handles it just fine, the
x86 one chokes in a known way:

Assembler: 
	"/homes/ro/leb128.s", line 2 : Syntax error
	Near line: "	.uleb128 L2 - L1"

I'll include the patch in tonight's Solaris bootstraps for good measure,
but it seems fine to me as is.

Thanks.
