configure: Always detect -no-pie toolchain support

Browse source 
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.

Backports commit b26341241bbfe9cc126479a0dbed5d40d547f242 from qemu
