    gcc-runtime: fix C++ header mapping for n32/x32 tune
    
    The SDK was unable to find the C++ header pieces correctly since it's
    using a generic compiler, not one specifically targeting the multilib
    vendor prefix and default tune.  This adds the right mapping to ensure
    SDKs work as expected. And fix problem in below configurations:
    
    multilib configuration 1:
    MACHINE="qemumips64"
    MULTILIBS ?= "multilib:lib32 multilib:libn32"
    DEFAULTTUNE_virtclass-multilib-lib32 ?= "mips"
    DEFAULTTUNE_virtclass-multilib-libn32 ?= "mips64-n32"
    MULTILIB_GLOBAL_VARIANTS_append = " libn32"
    require conf/multilib.conf
    
    ignoring nonexistent directory "<path>/sysroots/mips64-poky-linux/usr/include/c++/8.2.0/mips64-poky-linux/32
    
    multilib configuration 2:
    MACHINE="qemumips64"
    MULTILIBS = 'multilib:lib64 multilib:lib32'
    DEFAULTTUNE = 'mips64-n32'
    DEFAULTTUNE_virtclass-multilib-lib64 = 'mips64'
    DEFAULTTUNE_virtclass-multilib-lib32 = 'mips32r2'
    require conf/multilib.conf
    
    For this configuration:
    for target gcc-runtime, need to create symlink like mips64-poly-linux --> mips64-poky-linux-gnu32
    for target lib64-gcc-runtime, need to create symlink like mips64-poly-linux/32 --> mips64-pokymllib64-linux
    in order to avoid conflict during populate_sdk, create symlink for subfoler bits/ext for target gcc-runtime,
    this is ugly, but seems no better way to cover all kinds of configuration.
    
    single lib configuration:
    MACHINE="qemumips64"
    DEFAULTTUNE = "mips64-n32"
