build.log.xz

This is from a clean stage3. The default stage3 has C[,XX]FLAGS="-O2 -pipe -mcpu=ev4". With -mcpu="ev67" it builds. gcc-4.7.2 builds fine though.

The relevant part of the build.log is:

I can also confirm that 4.6.3 fails to build on alpha with "emake failed with bootstrap-lean"

CFLAGS="-mieee -pipe -O2 -mcpu=ev4"
