Rather than running 'uname', which returns information about the build
system, use the C compiler's -dumpmachine option, which outputs the
target triplet, which looks something like "x86_64-unknown-linux-gnu".
This enables us to detect the correct target OS when
the configured $(CC) is a cross compiler.
