* Added build_cross_tools_gcc4 script which builds gcc 4 and binutils

from the sources. Added respective configure option --build-cross-tools-gcc4. * Fixed running "configure --build-cross-tools" from another directory than the source dir. The parameter to the script was missing and thus the tools were created in <sources>/generated. * Removed stdc++ lib header dir ".../debug". One is supposed to include <debug/...> to get the debug headers. * The stdc++ lib header dirs are now listed one per line in the generated BuildConfig. This works around the 512 bytes jam line length limit. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@15020 a95241bf-73f2-0310-859d-f6bbb57e9c96
