csu: drop support for GCJ

Remove .jcr sections and related infrastructure. This has no impact on
existing binaries and the toolchain remains capability of linking them,
but would require different (or additional) csu files.

GCC removed GCJ from trunk in on September 30, 2016. Our support came
in with D17587 for compatibility with old object files. It was roughly
contemporaneous with GCC 6.5, the last release with GCJ support. At
this point we don't even have a compiler port capable of producing GCJ
binaries so there is no need to carry this around any more.

__CTOR_LIST__ is indeed unused in crtbegin.c; it marks the beginning of

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.
