your yasm is probably broken

I can confirm this with nasm.

output from libsdl build

Here's the full output.  I think it's because common.asm is compiled separately
and doesn't have the .note.GNU-stack ELF section.

------- Comment #6 From SpanKY 2006-06-08 02:42:59 0000 ------- 
should be fixed in cvs now

this was a two part bug in reality:
 - nasm users had common.asm compiled when it shouldnt have been causing a
0-byte asm file w/execstacks to be included
 - yasm users werent getting the 'no-exec-stack' markings included
