valgrind-3.6.1-x86-ldso-strlen.patch

Version:           3.6 SVN
OS:                Linux

With glibc 2.13.90 (Fedora 15), basically all invocations of valgrind fail complaining about strlen conditional jump depending on uninitialized when called from within the dynamic linker.  Recently ld.so started even on i?86 using optimized strlen which works on 4 bytes at a time.  The attached patch fixes this
by redirecting ld.so's strlen even on i?86 like it is already redirected e.g. on x86_64.

Reproducible: Always
