Default to armv7 cpu for NaCl when march=arm

Summary:
When the arch is given as "arm" clang uses the default target CPU from
LLVM to determine what the real arch should be (i.e. "arm" becomes
"armv4t" because LLVM's getARMCPUForArch falls back to "arm7tdmi").
Default to "cortex-a8" so that we end up with "armv7" in clang.

the nacl-direct.c test in clang also covers this case.
