Hi All, 


This patch adds the needed build system changes in order to compile
and create the new libraries for Semihosting v2.

This uses the new recursive build target in multi-build.in

The new spec files are:

For AArch32/ARM (m for mixed mode):
  - rdimon-v2m.specs
  - aprofile-validation-v2m.specs
  - aprofile-ve-v2m.specs

Regression tested on arm-none-eabi and no regressions.

OK for master?

PS. I don't have commit rights so if OK can someone apply for me?

Thanks,
Tamar
