Andrew Turner 31d62a73c2 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.
