    build: -no-pie is no functional linker flag
    
    Recent binutils changes dropping unsupported options [1] caused a build
    issue in regard to the optionroms.
    
      ld -m elf_i386 -T /<<PKGBUILDDIR>>/pc-bios/optionrom//flat.lds -no-pie \
        -s -o multiboot.img multiboot.o
      ld.bfd: Error: unable to disambiguate: -no-pie (did you mean --no-pie ?)
    
    This isn't really a regression in ld.bfd, filing the bug upstream
    revealed that this never worked as a ld flag [2] - in fact it seems we
    were by accident setting --nmagic).
    
    Since it never had the wanted effect this usage of LDFLAGS_NOPIE, should be
    droppable without any effect. This also is the only use-case of 
LDFLAGS_NOPIE
    in .mak, therefore we can also remove it from being added there.
