csu: add code to call constructors to be used by clang . clang-linked binaries were not calling global constructors, as the code to do so wasn't in csu/ and linked . it does work for gcc as it uses its self-supplied crt{begin,end} code . this commit copies netbsd's crt{begin,end}.S, which contains constructor/destructor calling code, called from .init and .fini sections already accumulated by the linker. the _init function was already called by the C startup code before calling main. . based on work by Antoine Leca
