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.
