    powerpc: Export __parse_hwcap_and_convert_at_platform to libc.a.
    
    Commit 67385a01d229751569b6aac067ffdcd813a15d7a added a new feature for
    powerpc, where we store HWCAP/Platform bits in the TCB.  In the dynamic
    linking case, we use the versioned symbol
    '__parse_hwcap_and_convert_at_platform' to verify if this feature is
    available.  However, the same symbol was not exported to libc.a, making
    it not possible for GCC to check for it prior to link time.
