Well exactly, V=1 gives more verbose output than V=2 :-)

One of the reasons this is useful is that with V=1 one can now simply
copy/paste the command line and modify it for test purposes. In addition,
you can easily verify that everything is on the command line as expected.

make V=2

  CC libc/sysdeps/linux/common/execve.os -D__USE_STDIO_FUTEXES__
-DHAVE_FORCED_UNWIND -D_LIBC_REENTRANT -DNDEBUG -DIN_LIB=libc


vs.

make V=1

I honestly think the latter to be more useful...
