Comment (by kencu):

 I'll gradually add to this list as I fill in systems for you:
 {{{
 $ cat testi386asm.S
         .text
         .align 4,0x90
         .globl _choose_tmpdir
 _choose_tmpdir:
         sbbl    $3+_vartmp, %esi
         ret
         .space 254

         .const
         .align 2
 _vartmp:
         .byte   47
 }}}
