Hi all,
Libstdc++ has been failing to build after I committed r271735. This
patch fixes
the build failure by checking if the current function is a thunk
before emitting the .cfi_b_key_frame directive.
Committed as obvious in r271780. Apologies for the failure.

* aarch64/aarch64.c (aarch64_post_cfi_startproc): Add
cfun->is_thunk check.
