factor: fix infinite loop on 32 bit powerpc
Both Debian and Ubuntu builds of coreutils 8.20 hang while running the test suite on powerpc, which is reproducible using 'factor 122'. This turns out to be somewhat related to http://bugs.gnu.org/12754, but not quite the same. uintmax_t is 64 bits, but the cntlzw instruction takes 32-bit operands, and the cntlzd option is only available on 64-bit hardware. * src/longlong.h: Add an _LP64 check around the PPC64 code, so that this falls back to the C implementations. * NEWS: Mention the fix.
