### 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.
xmkdir -p "${EPREFIX}"/usr/${CTARGET}/lib
xmkdir -p "${EPREFIX}"/usr/${CTARGET}/usr/lib
###
### We need some special riscv sauce here similar as in baselayout. Ugly.
### step 1: set up all multilib libdirs
### step 2: set up the compat symlink of the default abi for non-multilib
