CXXFLAGS="${CFLAGS}"
[edit] Sparc 64
CHOST="sparc-unknown-linux-gnu"
CFLAGS="-mcpu=ultrasparc -O2 -pipe"
CXXFLAGS="${CFLAGS}"
Note: The CHOST for Sparc64 is still sparc-unknown-linux-gnu, not sparc64-!

CFLAGS="-O2 -pipe -mschedule=7100LC -march=1.1 -fomit-frame-pointer"

[edit] Alpha ev67
CHOST="alpha-unknown-linux-gnu"
CFLAGS="-mieee -mcpu=ev67 -Wa,-mev6 -O2 -pipe "

This applies to ev68 (Compaq Alpha DS25) machines too. Without -mcpu=ev67 -Wa,-mev6 flags it cannot bootstrap at all.
