add tier 3 HelenOS compiler targets
Targets theoretically possible, but not provided yet: - 32-bit arm See also notes in the PR, I was unable to run anything non-trivial on ARM HelenOS, there are issues with the linker/loader, incomplete support of atomics, and overall a lot of confusion about the precise version of ARM architecture that the HelenOS builds target. - riscv, mips (These targets currently don't run HelenOS at all. HelenOS says it should work, but the builds are broken for quite some time now.)
