Remove NASM from the distribution

It's proven less useful than I originally hoped, and it's nearly always
better to use the GNU assembler instead. NASM doesn't support DWARF with
COFF, so it cannot be debugged with GDB. It's also ~100x slower than as,
which makes a huge different for generated assembly. With the autotools
fixes, it's now easy to natively build NASM from source using w64dk.
