            Bug ID: 58866
           Summary: sh64: Wrong genmultilib invocation
           Product: gcc
           Version: unknown
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: target
          Assignee: unassigned at gcc dot gnu.org
          Reporter: jbglaw@lug-owl.de

When I looked at
http://toolchain.lug-owl.de/buildbot/deliver_artifact.php?mode=view&id=131920 ,
I noticed there's excess whitespace in the 2nd argument of `genmultilib':

if test yes = yes \
   || test -n "mb=!mb m1=!m1 mb/m1=!mb/m1 m2a=!m2a mb/m2a=!mb/m2a

That should either be empty, or contain as many elements (space-separated) as
the first argument. This is on gcc111, an AIX box using gcc/g++ as the
compiler, but AIX's /bin/sh, which errors out (while bash silently ignores the
wrong shift implied by the excess space in arg#2). Building is done like this:

(GOLD, the rest of binutils and GCC were each build in separate, empty
directories.)
