arm: Fix multilib mapping for CDE extensions [PR100856].
On passing +cdecp[0-7] extension to the -march string in command line
options,
multilib linking is failing as mentioned in PR100856. This patch fixes this
issue by
generating a separate canonical string by removing compiler options which
are not
required for multilib linking from march string and assign the new string
to mlibarch
option. This mlibarch string is used for multilib comparison.
