Makefile: Quiet build hacks

Now the build is pretty:

  $ make
  make --no-print-directory all-am
    CC       libfdt/libfdt_la-fdt.lo
    CC       libfdt/libfdt_la-fdt_wip.lo
    CC       libfdt/libfdt_la-fdt_ro.lo
    CC       libfdt/libfdt_la-fdt_sw.lo
    CC       libfdt/libfdt_la-fdt_addresses.lo
    DTC      fake.dtb
    CC       src/pdbg-main.o
    DTC      p8-i2c.dtb
    CC       libfdt/libfdt_la-fdt_strerror.lo
    DTC      p8-fsi.dtb

Note that we now pass -q to the device tree compiler to ignore all of
the junk that it spits out.
