cross-canadian: update GNU name for ILP32 triplet

As discussed and agreed in Linaro Connect Budapest 2017 [1],
the GNU name for ARM64 with 32-bit ABI has been changed, e.g.,
from:
  aarch64_ilp32-linux-gnu
to:
  aarch64-linux-gnu_ilp32

The current code has "ilp32" as an OS variant; this change
updates that variant to include the underscore in order to
match the agreed convention.

More information about ARM64 ILP32 can be found here:

* https://wiki.linaro.org/Platform/arm64-ilp32
