When configuring a compiler for i586-linux, bootstrapping fails at:
./xgcc -B./ -B/usr/local/i586-linux/bin/ -isystem /usr/local/i586-linux/include
-isystem /usr/local/i586-linux/sys-include -L/home/robert/gcc/build/gcc/../ld

-Wmissing-prototypes -Wold-style-definition -isystem ./include -fPIC -g
-DHAVE_GTHR_DEFAULT -DIN_LIBGCC2 -D__GCC_FLOAT_NOT_NEEDED -I. -I.

in stage2.
I found that this happens when stage2 compiler is built with
-fomit-frame-pointer, as it is default for this configuration
(config/mh-x86omitfp). When this option is removed, bootstrapping is fine.
It seems that -fomit-frame-pointer does produce wrong-code when building stage2
compiler and thus stage2 compiler is broken.
Note that this does neither happen for i486-linux, nor for i686-linux, only for
i586-linux. Because of that it is essential to specify i586 explicitly when
trying to reproduce.

I ran into it too.
Btw, Roger, you forgot to add an entry to config/ChangeLog AFAICS.
