Bug 338615 suppress glibc 2.20 optimized strcmp implementation for ARMv7.

Add an add_hardwired_spec for strcmp in VG_(redir_initialise) for
ld-linux.so.3 and ld-linux-armhf.so.3 to use a simple strcmp
implementation in m_trampoline.S (compiled from the trivial .c code
to asm with gcc like the other implementations in that file).
