M680x0-llvm should understand the m68k-*-*-* triplet #57
Description
While working on the Rust backend for m68k based on the M680x0-llvm project, I ran into the problem that the LLVM target m68k-unknown-linux-gnu as I used in [1] was not understood by M680x0-llvm.
Since m68k-*-*-* is the common and widely used triplet name for m68k on Linux and other operating systems, I suggest the following change to the triplet code so that the logic matches the one for SystemZ/s390x:
