Application.mk:define main entry MAINNAME relatively

Browse source 
when a program has multiple MAINSRC for incremental compilation,
the PROGNAME of the compiled file may generate errors
-------------------- compile definition error ---------------------
cc -c -g CFLAGS INCLUDEDIR -Dmain=funA_main funB.c -o funB.c.path.o
                             ^^^^  ^^^^^^    ^^^^
-------------------------------------------------------------------
