[svn-r20502] Purpose:

    Add "silent make" mode configure option.

Description:

    Automake 1.11 has a new option available that allows for a
    silent make mode. This functionality needs to be explicitly
    enabled in configure.in via the use of the automake macro
    AM_SILENT_RULES, which is what this commit is adding.

    This introduces a new configure option: 

        --{en|dis}able-silent-rules

    This option is on by default, and simplies compile and link
    line outputs when building the library. Disabling this option
    will print full "verbose" output (i.e., full compile and
    linking lines for each target).

Tested:

    This was tested on jam & h5committested
