gcc-5.5.0-1: Rebuild with gcj (GNU-Java) support

- gcj and some other tools under bin are needed to bootstrap the
  openjdk builds (Using a 'regular' jdk does not work). Only
  drawback, one also needs the 'alien' ecj (Eclipse-Java) compiler
  to get a working gcj.

- g++ has been setup to use the old c++ abi per default, since
  I expect, that if it is used, its used to compile old stuff.
  (Note: -D_GLIBCXX_USE_CXX11_ABI=[0|1] works of course)
