xfsprogs: Make the compile output cleaner V3

xfsprogs: Make the compile output cleaner V3

We don't need to see every compiler command line for every file that
is compiled. This makes it hard to see warnings and errors during
compile. For progress notification, we really only need to see the
diretory/file being operated on.

Turn down the verbosity of output by suppressing various make output
and provide better overall visibility of which directory is being
operated on, what the operation is and what is being done to the
files by the build/clean process.

Sample output from a build:

....
Building libxlog
    [CC] xfs_log_recover.c
    [CC] util.c
    [LD] libxlog.la
Building libxcmd
    [CC] command.c
    [CC] input.c
    [CC] paths.c
    [CC] projects.c
    [CC] help.c
    [CC] quit.c
    [LD] libxcmd.la
....

Sample output from cleaning:

$ make clean
Cleaning include
Cleaning libxfs
Cleaning libxlog
Cleaning libxcmd
Cleaning libhandle
Cleaning libdisk
Cleaning copy
Cleaning db
....

If you want to see a noisy build (i.e. every command), use:

$ make V=1

and that will output all the commands that are now suppressed by
default.
