Hi,

attached you find the files I needed to add to crosstool-0.38
in order to build a sh4-linux gcc-4.0.2-glibc-2.3.5 tool chain.

Files attached:

sh4-gcc4.dat:
        * gcc4 needs --with-multilib-list=m4,m4-nofpu otherwise a linux
        kernel won't build as it uses the -m4-nofpu option.

gcc-pr21623.patch:
        * Kaz Kojima provided a patch [really, a workaround -dank] for http://gcc.gnu.org/PR21623

glibc-2.3.5-sh-memset.patch:
        * A patch for glibc-2.3.5 which corrects memset. From SUGIOKA Toshinobu.
        See content for rationale.
