Actually, I should mention that I haven't fully bootstrapped GCC with
this change (although it fixes the build failure I saw before).
libgcc/configure.ac also uses $target for something else so I'm not
sure it's okay to canonicalize it.  But at least the patch shows the
problem and a possible solution, so maybe you (or someone who
understsands the build scripts) can fully test it.
