The expression of interest looks like "e_5 = a::0_1 + b::1_2;" for
mmix-knuth-mmixware, while other targets have a "." instead of the
"::". ISTM the most useful change here is not to disable the test,
but to add an optional character in the matched expression to match
the "extra" ":". Also checked cris-elf to assert that the expression
still passes for an "ordinary" ELF target. Committed.
