Hi Richard,
I have all addressed all your review comments (in [1]) in the below patch.
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.
Regression tested on arm-none-eabi and found no regressions.
Ok for master?

Srinath.
