buildsystem: make output more readable

Generate short and readable compile messages:

  CC       IPL4asp_PT.o
  CCLD     TCCInterface.so
  CCLD     TELNETasp_PT.so
  CCLD     MGCP_Test

Instead of the very verbose messages we would get otherwise. Especially
the linking message clutters a whole page of terminal output without
this path:

   if ... g++ ... $ALL_OBJ_FILES; then : ; else ... $ALL_OBJ_FILES; fi
