[PATCH] makefile: Make default output compact and similar to Linux kernel.

[Georgi Chorbadzhiyski <gf@unixsol.org>]

This patch changes default make output to be similar to Linux kernel.
An example output looks like this:

ASM     crt/i386/crt1.s
COPY    crt/crt1.o lib/crt1.o
MKBITS  i386
MKTYPES include/bits/alltypes.h.sh
CC      src/aio/aio_cancel.c
CC      src/unistd/write.c
LD      lib/libc.so
BUILD   tools/musl-gcc
INSTALL /usr/local/musl/lib/libc.a
INSTALL /usr/local/bin/musl-gcc

If you want to see the executed commands use make V=1 or export V=1
before running make.
