[GCC][PATCH] arm: Fix multilib mapping for CDE extensions.

Hi All, 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 -march string only for multilib comparison. Regression tested on arm-none-eabi and found no regressions
