* libc/machine/arm/Makefile.am (lib_a_SOURCES): Add memchr-stub.c,
memchr.S.
* libc/machine/arm/arm_asm.h: Add ifdef to allow it to be included
in .S files.
* libc/machine/arm/memchr-stub.c: New file - just selects what to
compile.
* libc/machine/arm/memchr.S: New file - ARMv6t2/v7 version.
* libc/machine/arm/Makefile.am (lib_a_SOURCES): Add strlen-armv7.S.
* libc/machine/arm/strlen-armv7.S: New file.
* libc/machine/arm/strlen.c: Add ifdef optimised code so it isn't
for v7 or 6t2.
* libc/machine/arm/Makefile.in: Regenerate.
