With binutils-2.16.91.0.5 and 2.16.91.0.6, sometime strip fail

When it work
/tools/bin/find /lib /usr/lib /usr/share/rrdtool-* /install/initrd/lib \
	-type f \( -name '*.so' -o -name '*.so[\.0-9]*' \) \
	-ls -exec /tools/bin/strip --strip-all {} \; #2>/dev/null

...
(only libc was not yet stripped)
Then after many strip attempts

/tools/bin/find /lib /usr/lib /usr/share/rrdtool-* /install/initrd/lib \
	-type f \( -name '*.so' -o -name '*.so[\.0-9]*' \) \
	-ls -exec /tools/bin/strip --strip-all {} \; #2>/dev/null

/tools/bin/find: /tools/bin/strip terminated by signal 11

It look to corrupt libc-2.3.5.so. Any next attempt to strip again fail with the 
same signal 11 until glibc is rebuild. Then after the rebuild, it work most of 
the time. To be certain to reproduce the bug, I had to repeat the strip script 
in a `seq 1 20`loop.

All of the build is made similary to LFS-6.1 build (except binutil upgrade and 
stripping shared lib is not written in the book, but has been work for time 
with older LFS5.1 and strip 2.15.90.0.3 20040415)

strip part is made in a chroot inside the build environnement.
