Crap, so the option is also a Debian specific change? :/

We could do something like the kernel's cc-option to see if HOSTCC
accepts -no-pie - And if so, unconditionally add it to HOST_CFLAGS /
HOST_LDFLAGS.

cc-option is defined in scripts/Kbuild.include:

# cc-option
# Usage: cflags-y += $(call cc-option,-march=winchip-c6,-march=i586)

cc-option = $(call try-run,\
        $(CC) $(KBUILD_CPPFLAGS) $(CC_OPTION_CFLAGS) $(1) -c -x c /dev/null -o "$$TMP",$(1),$(2))
