[Buildroot] [git commit] toolchain: make target gcc a working option

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=243e4edc748b26f9a713bc268e5b7a6ff7d15956
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Make target gcc a more usable option.

* Nuke duplicate libgcc_s*.so* in /usr/lib since it confuses target gcc
* Copy *crt*.o files to the target system to unbreak gcc
