This change enables using llvm-objcopy instead of the gnu objcopy for building runtime. The benefit for cross build is that the host machine no longer needs to have cross-architecture gnu objcopy installed. There was an attempt to enable llvm objcopy in the past, but it was reverted due to a problem with objcopy in llvm 9 that incorrectly didn't strip debug symbols when `--strip-unneeded` option was specified. I have fixed that by adding `--strip-debug` in addition to the`--strip-unneeded`.
