--- Comment #4 from Loria <Loria at phantasia dot org> ---
I do encounter the same while trying to build a toolchain on OSX 10.10.5 and 
Xcode 7.2
crosstool-ng 1.22.1
binutils-2.25.1
gcc-4.9.3
glibc-2.22

CT_ARCH_CPU="arm1176jzf-s"
CT_ARCH_FPU="vfp"
CT_EXTRA_CFLAGS_FOR_BUILD="-fbracket-depth=1024"
CT_EXTRA_CFLAGS_FOR_HOST="-fbracket-depth=1024"


I already could generated the assembler text:
libc-start.s: Assembler messages:
libc-start.s:70: Error: invalid constant (af) after fixup
libc-start.s:145: Error: invalid constant (ff) after fixup

thats the file I attached
taking a look at the sourcefile shows (I marked the lines the assembler
dislikes):
.L3:
        ldr     r2, [r0], #4
        cmp     r2, #0
        bne     .L3

        ldr     r3, [r3]
        cmp     r2, #0
        clz     r3, r3
        mov     r1, #1
        moveq   r1, r2
        mov     r3, r3, lsr #5

        mov     r2, r1
        bl      __cxa_atexit

it looks to me the two instructions 
        mov     r2, #175
        (mov    r2, #0xAF)
and
        bic     r3, r3, #255
        (bic    r3, r3, 0xFF)
are correct (immediate value fits into 8 bits, rotate i would expect to be 0 in
both cases)
