Fix for unreferenced linker lib -ltinfo

This fixes the linker for NCURSES:
/data/apps/binutils/2.23.2/bin/ld: bam_tview_curses.o: undefined reference to symbol 'keypad'
/data/apps/binutils/2.23.2/bin/ld: note: 'keypad' is defined in DSO /lib64/libtinfo.so.5 so try adding it to the linker command line
/lib64/libtinfo.so.5: could not read symbols: Invalid operation
