package/gcc/gcc-final: add a target variant in charge of target installation

Browse Source 
This commit adds a target package "gcc-final", which is a target
package responsible for installing the gcc runtime libraries to
STAGING_DIR and TARGET_DIR. This task was so far done by the host
gcc-final package.

The motivation for splitting it up into a target package is to be able
to properly handle the licensing situation of GCC, where the host part
of GCC (the compiler itself) is under GPLv3, but the runtime libraries
on the target are under GPLv3-with-exception. So far, we were not
handling at all the license of gcc.

So what this commit does is:

 * Add a gcc-final target package, which is depended on by the
   toolchain-buildroot package, and which depends on
   host-gcc-final.

 * Moves to gcc-final the logic for installing target/staging
   libraries
