There is a function defined in builtins.def as
__builtin_extract_return_addr. The function is used by that name in
libgcc/unwind-dw2.c. For some reason the documentation for this
function uses the name __builtin_extract_return_address. This patch
corrects the documentation to match the definition and usage.
Bootstrapped on x86_64-unknown-linux-gnu. Committed as obvious.
