    libgcc-common.inc: Fix broken symlinks for multilib SDK
    
    This patch fixes broken "32" symlinks for multilib settings:
    
    MACHINE = "qemuarm64"
    require conf/multilib.conf
    MULTILIBS = "multilib:lib32"
    DEFAULTTUNE_virtclass-multilib-lib32 = "armv7a"
    
    and
    
    MACHINE = "qemux86-64"
    require conf/multilib.conf
    MULTILIBS = "multilib:libx32"
    DEFAULTTUNE_virtclass-multilib-libx32 = "x86-64-x32"
    
    [YOCTO#8642]
    [YOCTO#10380]
