[Buildroot] GCC in my pc has been used during my customize package building

[hoperun <hoperun@unicorn.osuosl.org>]

Hi all,

I am new guy in buildroot developing, and maybe have some stupid
questions.

I tried to integrate some package in github into buildroot for my
requirements. Just like the following:

    ################################################################################
    #
    # ioc-cbc-tools
    #
    ################################################################################
    IOC_CBC_TOOLS_VERSION = master
    IOC_CBC_TOOLS_SITE =$(call github,intel,ioc-cbc-tools,$(IOC_CBC_TOOLS_VERSION))
    IOC_CBC_TOOLS_LICENSE = BSD-3
    IOC_CBC_TOOLS_LICENSE_FILES = COPYING
    
    define IOC_CBC_TOOLS_BUILD_CMDS
    	$(TARGET_MAKE_ENV) $(MAKE) -C $(@D) all
    endef
    
    define IOC_CBC_TOOLS_INSTALL_CMDS
    	$(TARGET_MAKE_ENV) DESTDIR=$(TARGET_DIR) $(MAKE) -C $(@D) install
    endef
    
    $(eval $(generic-package))

but the makefile in this project just like this:

    $(OUT_DIR)/cbc_lifecycle: cbc_lifecycle.c
    	gcc -o $@ $(CFLAGS) $(LDFLAGS) cbc_lifecycle.c -pthread -lacrn-mngr
    
    clean:
    	rm $(OUT_DIR)/cbc_lifecycle

It take "gcc" directly. But there isn't gcc in my "buildroot/output/host/bin".

    buildroot $ find  output/host/ -name "*gcc"
    output/host/libexec/gcc
    output/host/lib/gcc
    output/host/bin/x86_64-linux-gcc
    output/host/bin/x86_64-xxx-linux-gnu-gcc

Could anybody give me some hints?

Thanks for any comments.

Thanks,
Jerry
