Commit 67385a0 added a new feature for Power, where we store HWCAP and 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. Commit c676e65 fixes this.
