Add nacl-clang testing to SCons
This CL adds a nacl_clang flag to SCons to use nacl-clang.
It adds an implicit dependence on -lpthread to nexes because nacl-clang
always links with it (because libc++ requires it). It's also enabled
for PNaCl; if this ends up working out well for nacl-clang maybe we can
remove the really ugly special-casing for pthread_private in pnacl-ld.
It modifies or disables a few tests, so that everything now build with
nacl-clang (or has a bug filed for why not).
It also ifdefs out the .init and .fini sections from crti/crtn, because
we do not use them with clang.
