Requires TuxMake/TuxSuite support first: https://gitlab.com/Linaro/tuxmake/-/issues/205

Once it is supported there, the following configurations need to be disabled to build at the time of writing this:

CONFIG_CRASH_DUMP=n
CONFIG_RELOCATABLE=n

CONFIG_MODULES=n

Additionally, the support for LoongArch in ld.lld needs to be merged to use full LLVM=1, otherwise we may be able to use GNU ld but I have not tested that yet.

That is only one piece, we need ld.lld support merged into LLVM main to allow us to use clang-nightly, as Debian does not ship loongarch64-linux-gnu binutils or GCC.

FYI: the LLD LoongArch port has been upstreamed just in time for the LLVM 17 release. We will continue the work on enabling the other bits ;-)
