otherwise, we create empty directories where build.list
doesn't exist, like on coreboot.
we already create a directory when needed, when actually
copying elf files, so let's just leave it at that.

many places in cbmk used err, because older versions
of x_ did not handle globbing properly.
however, use of x_ is preferable on trivial commands.
the only time err() should be called is what it has
to be, when x_ can't work, or when a more useful error
message is needed, for context.
