I am building some cross-compilers using the crosstool scripts (http://kegel.com/crosstool/) and I think that they are generally useful to Debian.
The source package is name crosstool and it produces the gcc-powerpc and gcc-powerpc64 packages. Should add more as soon as possible. The crosstoll scripts are licenced under the GPL. The packages can be downloaded from ftp.las.ic.unicamp.br/pub/crosstool Currently I am trying to correctly strip the binaries. Other things in the TODO are 1) check the build-depends 2) use all debian's patches to binutils, gcc, glibc and the kernel. 3) use only debian's patchs (it is a bug if a debian package does no cross-compile, right?) 4) add more archs. Thanks for any comment. Rafael
