Specify NOLIBCSANITIZER in lib/csu The low-level libraries in csu are used in non-sanitized code.

Disable MKSANITIZER in lib/csu These low-level libraries are expected to be not touched by a sanitizer. Every libc program not using sanitizers cannot work with sanitized csu.

add a hack so that old- and new-toolchain alphas do the right thing: include bsd.own.mk early on, and if !alpha or if !ELF_TOOLCHAIN, build c++rt0.o. ELF alphas don't use the 'normal' C++ runtime startup routines. Eventually, there should be better ways to distinguish what toolchain and object format is in use, and the Alpha C++ startup code changes should be merged with that used by the other ports.

If object_fmt == elf and we have machine_elf, build that one.

Switch i386 and x86_64 to the new CRT layout. The crt0.c body is shared between all platforms and a small assembler stub in crt0.S is used for setting up the proper stack and whatever else MD needs. Extract crti.S and crtn. from the old dot_init.h files. Prepare other platforms that use the 6-argument form of __(_)start for this. Rewrite the crtbegin and crtend modules in assembler to make them compiler independent. Document the interface in README.
