Robert P. J. DAY says:
According to Mike Frysinger, this patch was removed from Gentoo in the
2.3.x series and didn't seem to cause any adverse effects. So toss it
from the patch directories for glibc 2.5 and up.

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.
