configure: Always detect -no-pie toolchain support
The CFLAGS_NOPIE and LDFLAGS_NOPIE variables are used in pc-bios/optionrom/Makefile, which has nothing to do with the PIE setting of the main qemu executables. This overrides any operating system default to build all executables as PIE, which is important for ROMs. Reviewed-by: Philippe Mathieu-Daudé <philmd@redhat.com> Reviewed-by: Thomas Huth <thuth@redhat.com> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>
