UX:as: ERROR: (EOF):undefined name: .LPR0

The only occurrences of LPR0 are 4 uses.  There are no definitions:
getlogin_r:
        pushl   %ebp
        movl    %esp, %ebp
        pushl   %ebx
        subl    $4, %esp

        subl    $8, %esp


	
>How-To-Repeat:
	Build the attached file.  Assemble the resulting output.

$ ./cc1 -quiet -fPIC /tmp/crtstuff.i
(robertl) rjlhome:/play/tmp/7/gcc
$ as -belf /tmp/crtstuff.s
(EOF):undefined name: .LPR0

Can be duplicated somewhat under Linux. The difference is that GAS apparently
lets you jump to labels that don't exist. Build a cross thusly:
/play/egcs/configure --target=i686-pc-udk --with-as=/bin/as \
   --enable-languages=c
$ ./cc1 -fPIC /tmp/crtstuff.i
   [ ... ] 
$ grep LPR0 /tmp/crtstuff.s
        call    .LPR0
        call    .LPR0
        call    .LPR0
        call    .LPR0
