memcheck, and they are hard to get rid of and hard to suppress. So add a bootstrap strlen function and redirect to it right from the start. This fn only replaces the strlen in ld.so; the "normal" redirect mechanism still replaces the strlen that glibc supplies. This commit finally (!) makes memcheck behave sanely on ppc32. git-svn-id: svn://svn.valgrind.org/valgrind/trunk@4445
