PowerPC32 ld test fails with --enable-targets=all

Three pppc32 ld tests fail when spe support is included in the linker
due to this snippet in ld/emulparams/elf32ppc.sh.

if grep -q 'ld_elf32_spu_emulation' ldemul-list.h; then
  DATA_START_SYMBOLS="${RELOCATING+*crt1.o(.data .data.* .gnu.linkonce.d.*)
    PROVIDE (__spe_handle = .);
    *(.data.spehandle)
    . += 4 * (DEFINED (__spe_handle) || . != 0);}"
fi
