2015-07-30StdLib/LibC: Add software floating point library from NetBSDNetBSD project
Floating point processing is not supported on ARM for UEFI. In order to support UEFI applications in AppPkg we use this library to provide the required functionality. Changes as compared to the NetBSD version: - Formatting changes (tabs to spaces, DOS line endings etc). - Disable exceptions as described in the float_raise() function. - Disable definition of 'Symbolic Boolean literals' in milieu.h.
