I had the same problem on my PowerPC Linux machine and the workaround
I'm using now is to run make with the additional flag STAGE1_CFLAGS=-O.
The problem (thanks to Andreas Schwab and Michael Matz for help) is that
.glink and .text is too far away from each other (> 32 MB in the
non-optimized case) and therefore building of e.g. cc1-dummy fails.
Adding -Wl,--relax to the cc1-dummy build helped for that binary but I
found no way to get this properly into the Makefiles (and make
LDFLAGS="-Wl,--relax" gave an error in configure later on),
