MFC the BSD crtbegin to stable/12 but keep it disabled.
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.

Add used to CTOR_LIST__ and DTOR_LIST
Enabling BSD_CRTBEGIN on amd64 resulted in
error: unused variable 'CTOR_LIST'.
CTOR_LIST is indeed unused in crtbegin.c; it marks the beginning of
the .ctors array and is used in crtend.c. Annotate DTOR_LIST as
well for consistency.

Mark the function called by the MIPS .init/.fini sequence with .local.
As with r328939 we need to mark local symbols as such. Without this the
assembly parser treats the symbols as global and created relocations
against these private symbols.

r342974:
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.
