Application.mk:define main entry MAINNAME relatively

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 ^^^^ ^^^^^^ ^^^^ ------------------------------------------------------------------- use the MAINOBJ:PROGNAME mapping variable to define the main entry name Signed-off-by: xuxin19 <[email protected]>
