[dpdk-dev] Compile error with CONFIG_RTE_BUILD_COMBINE_LIBS=y

[Qiu, Michael]

Hi, Thomas

I see you recently merged one commit:

commit 8f1c704fb0f1b867471fc692ed2c0fc5610831e2

    mk: fix external library build when combine is enabled
    
    The object files are copied to prepare the internal combined library.
    It must be disabled when building an external library.
    
    It has been seen because the directory was missing:
        examples/ethtool/lib/x86_64-native-linuxapp-gcc/build/lib:
        No such file or directory
    
    Signed-off-by: Thomas Monjalon <thomas.monjalon at 6wind.com>

It lead compile error when open CONFIG_RTE_BUILD_COMBINE_LIBS.

See below:

make -j install T=x86_64-native-linuxapp-gcc
