[libvirt] [PATCH 1/4] build: yet another cgroup conditional compilation fix

[Eric Blake]

From: "Daniel P. Berrange" <berrange at redhat.com>

Linking fails on FreeBSD:
   CCLD     libvirt.la
  /usr/bin/ld: ./.libs/libvirt_util.a(libvirt_util_la-vircgroup.o):
  relocation R_X86_64_PC32 against `virCgroupPartitionEscape' can not be
  used when making a shared object; recompile with -fPIC
  /usr/bin/ld: final link failed: Bad value
