Drop unnecessary EXTERN symbols
Currently, NASM always issues as an unknown symbol any symbol declared EXTERN. This is highly undesirable when using common header files, as it might cause the linker to pull in a bunch of unnecessary modules, depending on how smart the linker is. Add a new REQUIRED directive which behaves like the old EXTERN, for the use cases which might still need this behavior. Signed-off-by: H. Peter Anvin (Intel) <hpa@zytor.com>
