The softfloat routines and some other routines supplied by LibC
will satisfy references to compiler intrinsics that are emitted
by the compiler backend, which under LTO means that the link-time
code generation may emit references to symbols that have been
optimized away already.
Work around this by building the ARM and AARCH64 versions of LibC
and the softfloat library without LTO.

- Use NetBSD software floating point library to provide floating point
operations not handled directly by hardware floating point enabled
GCC compiler.

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.
