-arch-cross provides -arch-dcvX

No, I changed paths in 1.26 (first release after paths in debian toolchain 
changed).

You have too old version of libgcc1-arm-cross, that does not provide 
libgcc1-arm-dcv1 (and, btw, installs to /usr/arm-linux/)

I've updated gcc-4.0 source package to build -arch-cross packages with 
proper provides, but still could not find time for 3.4/3.3. Help on that 
is welcomed.

Some prebuilt packages are at

No, because 1.2.4 will be greater than 1.2.3-dcvX
