[PATCH v3 02/19] Allow make-link-multidir to make subdirectories

[Palmer Dabbelt]

The RISC-V Linux ABI doesn't define any libraries that go directly in
lib, instead they go into lib/ilp32 or lib/lp64.  This casuse
make-link-multidir to fail when attempting to make library directories
when building a static libc on multilib RISC-V systems.

This patch adds '-p' to mkdir so it will make subdirectories.  I've
added "." as an argument so mkdir won't error out if no directories are
provided -- I think "mkdir -p ." should always do nothing.
