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.
Ok for master?
Not as it stands. More comments below.

Srinath.

This just won't fly. Firstly, we don't use ifdefs this way in the main
code base anymore (it needs to be done through hooks if it can't be made
completely generic). Secondly, it makes reference to a machine-specific
switch name directly from machine-independent code. I don't currently
have a strong suggestion to make at this point, though, sorry. Perhaps
someone else can suggest a way forward.
