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.

The tests haven't been run them, but this is enough to build them so I can

r339954:
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.

The BSD crtbegin/crtend code now builds on all architectures, however
further work is needed to check if it works correctly.

r340840:
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.

r340910:
Add the missing 0 at the end of the .jcr section.
Without this the dynamic library test was failing as it was calling
_Jv_RegisterClasses multiple times.
r340911:
Re-enable the dynamiclib tests. These should be fixed by r340910.
r341424:

files that haven't been implemented.

r342773:
Add explicit csu test dependency
lib/csu/tests/dynamiclib requires libh_csu.so be built first. I'm not
sure this is the most correct/best way to address this but it solves
the issue in my testing.

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.
