I'd even extend it to say that cross compilers should not search
$prefix/include...  I don't know if there's a general convention about
this (BFD recently changed its behavior here, although I don't really
like the new behavior either) but I've always thought that since
$prefix/include and $prefix/bin and $prefix/lib are siblings,
$$prefix/include should be headers for the versions of things in
$prefix/lib.  Target headers belong in $prefix/$target_alias/include.
