Bah, the arm-qemu-linux-uclibc sample isn't usefull. Base your work on the armeb-unkown-linux-uclibc sample instead.

5 Subject: Crosstool sh4-linux-gcc-4.0.2-glibc-2.3.5 patches
9 attached you find the files I needed to add to crosstool-0.38
10 in order to build a sh4-linux gcc-4.0.2-glibc-2.3.5 tool chain.
15 * gcc4 needs --with-multilib-list=m4,m4-nofpu otherwise a linux
16 kernel won't build as it uses the -m4-nofpu option.
19 * Kaz Kojima provided a patch [really, a workaround -dank] for http://gcc.gnu.org/PR21623
21 glibc-2.3.5-sh-memset.patch:
22 * A patch for glibc-2.3.5 which corrects memset. From SUGIOKA Toshinobu.
23 See content for rationale.
27 -- Here's patch 1 of 2, plus URLs showing where it is in CVS --

31 2005-09-30 Kaz Kojima <kkojima@gcc.gnu.org>
33 * config/sh/sh.c (sh_register_move_cost): Add case for moving
34 from T_REGS to FP register class.
