libre/pacman: Add preliminary ppc64le support.

This has not been built or tested on ppc64le, however it enables
to create a ppc64le chroot with librechroot.
While creating the chroot, it does install the packages:
$ sudo librechroot -A ppc64le -n parabola-ppc64le make
[...]
(  1/134) installing linux-libre-api-headers [################################################] 100%
(  2/134) installing tzdata                  [################################################] 100%
[...]
and the packages binaries are indeed for ppc64le:
$ file /var/lib/archbuild/parabola-ppc64le/root/usr/bin/bash
/var/lib/archbuild/parabola-ppc64le/root/usr/bin/bash: ELF 64-bit [...], 64-bit PowerPC [...]

However, qemu(through qemu-user-static-binfmt) currently fails
at running any of theses binaries with:
"error: command terminated by signal 4: Illegal instruction".

This also affects the packages post-installation and hooks.
