Greg Kurz cd1064b16f packaging: Configure QEMU with --enable-pie ...

We explicitely set the Postion Independant Executlable (PIE) options
in the extra CFLAGS and LDFLAGS that are passed to the QEMU configure
script for all archs. This means that these options are used pretty
much everywhere, including when building the sample plugins under the
test directory. These cannot be linked with -pie and break the build,
as experienced recently on ARM (see PR #2732).

This only broke on ARM because other archs are configured with
--disable-tcg : this disables plugins which are built by default
otherwise.

The --enable-pie option is all that is needed. The QEMU build system
knows which binaries should be created as PIE, e.g. the important
bits like QEMU and virtiofsd, and which ones should not, e.g. the
sample plugins that aren't used in production.

Rely on --enable-pie only, for all archs. This allows to drop the
workaround that was put in place in PR #2732.

Fixes: #2757
