Summary:  XCALL resolved incorrectly in avr5/libc.a

Original Submission:  In a larger ATmega128 project,
the original submitter of this bug (in AVRfreaks) suddenly
got:

itoa.o(.text+0x20): relocation truncated to fit: R_AVR_13_PCREL __udivmodhi4

This corresponds with

        XCALL   _U(__udivmodhi4);  quotient in r23:r22, remainder in r25:r24
                                ;  clobbered: r0, r21, r26, r27
                                ;  call-used but preserved: r18, r19, r20, r30, 
r31
        subi    r24, 0xd0       ; + '0'

in libc/misc/itoa.S.  XCALL is supposed to be an absolute
call for the avr5 target, but extracting itoa.o from
avr5/libc.a, and disassembling it reveals that it has
been assembled as an rcall.

Other functions migh probably be affected as well.
