I spent part of the weekend trying to build a toolchain for the sh4 with different results: the only release that successfully built a toolchain was rev 1.20.0 (but then i had problems compiling a kernel with it, see below), while the process failed in all the other releases. After every checkout i did a 'git clean -fdx; ./bootstrap; ./configure --enable-local; make; ./ct-ng sh4-unknown-linux-gnu; ./ct-ng build;" < 1.19.0: weird errors here... 1.19.0: ...
