Normally only changes to the build_cross_tools* scripts and, of course, to the
buildtools sources themselves should require rebuilding them, since all Haiku
changes should maintain binary compatibility. In this case, as an exception,
binary compatibility was not maintained (the API didn't really exist/was broken
in BeOS and previous Haiku versions).
For building gcc a subset of headers/config, headers/posix, and headers/os is
used. Which headers exactly is not exactly trivial to determine. Binary
incompatible changes in those may require a rebuild of the tools, though, as
written above, should not normally be made.
