crossdev: unconditionally create /usr/${CTARGET}/{lib,usr/lib}
Copying note as-is here:
```
Create directories usually created by sys-apps/baselayout
Why we do that at all:
For multilib-aware targets (ppc64, s390x, sparc64, x86_64) Gentoo
normally uses libdir=lib64.
For crossdev it means /lib and /usr/lib does not get created at all
but gcc relies on their presence by refering to =/lib64 as
=/usr/lib/../lib64 when builds itself (see https://bugs.gentoo.org/652724)
Thus we create non-symlinked layout early.
```
Before the change 'crossdev -t powerpc64le-foo-linux-gnu' failed
at gcc-stage2 as:
```
... \
-shared -nodefaultlibs -Wl,--soname=libgcc_s.so.1 \
-o ./libgcc_s.so.1.tmp \
... \
/usr/libexec/gcc/powerpc64le-foo-linux-gnu/ld:
cannot find crti.o: No such file or directory
access("/usr/powerpc64le-foo-linux-gnu/usr/lib/../lib64/crti.o", R_OK) = -1
ENOENT (No such file or directory)
```
The change adds empty directory '/usr/powerpc64le-foo-linux-gnu/usr/lib'
to make ld probing finally find 'crti.o' in $SYSROOT.
