build: binary modules manpage

binary: objs/nginx

objs/nginx: objs/src/core/nginx.o ... objs/src/http/ngx_http.o

$(LINK) -o objs/nginx (...o)-ldl -lpthread -lcrypt -lpcre -lz -Wl,-E

下面是每个.o文件的编译规则

objs/ngx_modules.o: $(CORE_DEPS) objs/ngx_modules.c

(CC) -c $(CFLAGS) $(CORE_INCS) -o objs/ngx_modules.o objs/ngx_modules.c

...

objs/src/http/ngx_http.o: $(CORE_DEPS) $(HTTP_DEPS) src/http/ngx_http.c

$(CC) -c $(CFLAGS) $(CORE_INCS) $(HTTP_INCS) -o objs/src/http/ngx_http.o src/http/ngx_http.c

...

manpage:objs/nginx.8

objs/nginx.8: docs/man/nginx.8 objs/ngx_auto_config.h

sed -e ...替换现有文件内容
