rust-cross/rust-common: Merge arm target handling code to fix cross-canadian

rust-cross had special handling for armv7 targets but we also need this
for cross-canadian. Merge the code into the main function so everything is
consistent.

Also then fix the arm definition to be arm-eabi since ABI is correctly
being looked up.
