nasm 2.09 compatibility

nasm-2.09 makes `elf' alias to `elf32', thus __OUTPUT_FORMAT__ macro
becomes `elf32' instead of `elf' (on x86). Unmatched macro value causes
omitting .note.GNU-stack marker and creates ELFs with executable stack.
This is unneeded and attracts security policies like SELinux.
