# particular, they make sure that gold can link "difficult" object
# files, and the resulting object files run correctly.  These can only
# run if we've built ld-new for the native architecture (that is,
# we're not cross-compiling it), since we run ld-new as part of these
# tests.  We use the gcc-specific flag '-B' to use our linker instead
# of the default linker, which is why we only run our tests under gcc.
