[PATCH 00/10] Enable multilib for target gcc

[nitin.a.kamble@intel.com]

From: Nitin A Kamble <nitin.a.kamble@intel.com>

These commits enable the target gcc for multilib compilation.

The tune file definitions are rearranged for easy parsing by multilib code.

Multilib setup code is added for target gcc recipe. This code looks at the
multilib configuration defined in local.conf and generates multilib setup files
for target gcc accordingly.

Also target libgcc recipe is extended to have correct paths for non-default
gcc multilib options.

All this code added for multilib setup is inactive if multilib is not enabled
in the local.conf

This has tested to work with x86 & x86-64 enabled multilib configuration
for x86-64 machine.

Thanks,
Nitin
