+- pass explicit -pie flag to CFLAGS and hack `make` invocation so that
+  /usr/bin/expect actually becomes a PIE binary. This is especially awkard
+  since the expect build system implicitly passes -fPIC which breaks our
+  gcc-PIE package, but does not pass -pie while linking the executable.
+  Shared libraries are also not linked with -shared so we need to explicitly
+  pass this, too, to avoid build breakage (bsc#1184122).
