All the cross packages got removed. gcc-1[1-4] also got removed.

llvm-toolchain-14 is also gone, for all architectures.
For dependencies, we are left with only gcc-15, gcc-defaults, zlib and
glibc, I'll work on filling the corresponding bugs against
ftp.debian.org as the next step.
For build-dependencies, llvm-toolchain-{19,20} still need to be fixed.
