I haven't been able to find evidence of "-nopie" ever having been a
supported compiler option. The correct spelling is "-no-pie".
Furthermore like "-pie" this is an option which is solely passed to the
linker. The compiler only recognizes "-fpie" / "-fPIE" / "-fno-pie", and
it doesn't infer these options from "-pie" / "-no-pie".
Add the compiler recognized form, but for the possible case of the
variable also being used somewhere for linking keep the linker option as
well (with corrected spelling).
