    sdk: do not strip static libraries
    
    Do not strip static libraries shipped with the SDK in order to preserve the
    archive index. If we strip the index of the shipped libraries, host programs
    will fail to link these libraries with errors like:
    
        libssl.a: error adding symbols: Archive has no index; run ranlib to add one
    
    The error was found while investigating a Python host build failure within
    the SDK environment.
