[Bug bootstrap/41243] New: [4.5 regression] Revision 151313 caused random compare failure

[hjl dot tools at gmail dot com]

On Linux/ia32 and Linux/x86-64, I got random
compare failures during bootstrap:

Comparing stages 2 and 3
warning: gcc/cc1obj-checksum.o differs
warning: gcc/cc1plus-checksum.o differs
warning: gcc/cc1-checksum.o differs
Bootstrap comparison failure!
x86_64-unknown-linux-gnu/32/libgcc/_umoddi3.o differs
make[5]: *** [compare] Error 1

Comparing stages 2 and 3
warning: gcc/cc1plus-checksum.o differs

warning: gcc/cc1-checksum.o differs
Bootstrap comparison failure!
i686-pc-linux-gnu/libgcc/bid128_fma.o differs

It is not reproducible.
