+ exit 1

A recent change to libobjc/configure.ac within this time-frame looks suspicious:
! [# we know we are compiled as a target library, so the toplevel build
directory
! # is ../..
! if test -f ../../$host_subdir/gcc/Makefile

That's false; it's not true for multilibs, which are nested an arbitrary level
within the target subdir.
