The stub libc.so (needed for libgcc_s) needs to be passed the same compiler flags as glibc itself when building for multilib.
For multilib on the target side, create "lib64" (for 64-bit build or host architectures) and "lib32" (for 32-bit emulation on 64-bit) as symlinks to "lib" and "lib/32", respectively.
Copy the gnu/{lib-names,stubs}-${multi_dir} headers needed by
gnu/{lib-names,stubs}.h.

Pin GCC to 4.5.3 and binutils to 2.22, the last versions working. There are multiple bugs affecting bfin configuration; while [3] is fixed on trunk in GCC (but not backported to gcc-5-release branch yet), [1] and [2] do not have fixes yet. References: [1] https://sourceware.org/bugzilla/show_bug.cgi?id=17334 (binutils bug) [2] https://gcc.gnu.org/bugzilla/show_bug.cgi?id=47779 (gcc bug #1) [3] https://gcc.gnu.org/bugzilla/show_bug.cgi?id=55144 (gcc bug #2)

I accidentally submitted this to ct-ng upstream but that's fine. Description is there: crosstool-ng#119
