Subject: build: -no-pie is no functional linker flag

Git-commit: bbd2d5a8120771ec59b86a80a1f51884e0a26e53

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.
