@Use --sysroot in cpp/gcc/gxx cross-compiler wrappers.

Now that NetBSD supports --sysroot we don't need to mess with the
partial measures of -nostdinc, -isystem, &c.

1.1
log
@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
