Don't indent the .globl marker

It doesn't need to be, although I'm not sure what "needs" to be how and
stuff.  For example, I think there "should" be a .text section, but it
doesn't seem to be required.

  (display "\n"))
(define (compile-program x)
  (display "\t.globl scheme_entry\n\n")
  (display ".globl scheme_entry\n\n")
  (display "scheme_entry:\n")
  (emit "movl $~a, %eax" x)
  (emit "ret"))
