Add core of the infrastructure support for cross-compilation.
- USE_CROSS_COMPILATION activates it, CROSS_DESTDIR specifies root of the target filesystem - derive _CROSS_DESTDIR from CROSS_DESTDIR or MAKEOBJDIR - buildlink3.mk prefixes the files to symlink with _CROSS_DESTDIR - compiler/gcc.mk knows about the target prefix (e.g. i386--netbsdelf) - PKG_DBDIR is prefixed with _CROSS_DESTDIR - package-install and bin-install are not called with su - install and strip are redirected to the tool version - links for the target specific ar, as, ld, nm, objdump, ranlib and strip are added - compiler wrapper detect if linking is requested or not - special command sinks for CPP and CC/CXX add the cross-compile magic: - modify include dirs to get the target /usr/include - modify linker dirs and runpath to use target /usr/lib at link time, but keep correct rpath entries Supported-by: Google SoC 2007 Basic tests by he@ on Sparc. Review from jlam@.
