Makefile.am: added custom rule with -fwhole-program

To make the ncmpc binary even smaller, you can compile all sources at
once with "--combine -fwhole-program".  Unfortunately, automake does
not support this mode.  For further experiments, this patch adds a
custom rule which creates the binary named "ncmpc-tiny" this way.
