gcc: Heavy Makefile modification, now builds and runs on target.

* Use the same GCC version as the Attitude Adjustment toolchain.
* Use REAL_GNU_TARGET_NAME that contains the _uclibc suffix.
  Otherwise the linker on the target is not found.
* Revamped install section to install only needed binaries and omit
  static .a libs.
