We have two copies of fenv.h for every architecture, one of which isn't used. We also have unused makefiles and files for architectures we don't support. This patch removes all the obviously useless files. Bug: http://code.google.com/p/android/issues/detail?id=38196 Change-Id: I1919b6621ba513aa24aa947a34815bc51191487c
