r339738:
Implement a BSD licensed crtbegin/crtend

These are needed for .ctors/.dtors and .jcr handling. The former needs
all the function pointers to be called in the correct order from the
.init/.fini section. The latter just needs to call a gcj specific function
if it exists with a pointer to the start of the .jcr section.

This is currently disabled until __dso_handle support is added.

Create crtsavres.o for powerpc builds

Summary:
GCC expects to link in a crtsavres.o on powerpc platforms. On
powerpc64 this is an empty file, but on powerpc and powerpcspe this does contain
some save/restore functions, which may not actually be necessary for newer
modern GCC and clang. This appeases the in-tree gcc, though, and is needed in
order to switch to the BSD CRTRBEGIN.
