[libvirt] [PATCH] Fix '-pie' build with clang

[Martin Kletzander]

Commit 97e70a593589e8f0432a748b4b93c3cdc18b9e5a added the option -pie to
CFLAGS and LDFLAGS, however '-pie' is just a linker option.  That
wouldn't be a problem.  However, clang is checking for that and outputs
an error or unused argument:

error: argument unused during compilation: '-pie'
