So this part was added as part of the discussion in this bug report: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=453267 >From what I remember, that first branch was specifically in support of building cross compilers. I don't have recent knowledge of cross-building and cross-compilers so I have no idea whether that's still useful in some cases or not. > I attempted a full architecture cross bootstrap (for m68k as it is > quick) with that first branch deleted and it succeeded.

The right thing to try to validate whether we can remove the code is building a cross-compiler (and not cross-building a compiler).
