abi_check is failing on alpha:

# of added symbols:              505
# of missing symbols:            0
# of incompatible symbols:       22

FAIL: abi_check

These failures are all due to incompatible std::numeric_limits object versions,
i.e.:

_ZNSt14numeric_limitsIgE14max_exponent10E
std::numeric_limits<__float128>::max_exponent10
version status: incompatible
GLIBCXX_3.4
type: object
type size: 4
status: added

According to abi_check, functions with __float128 arguments should be versioned
as GLIBCXX_LDBL_3.4. Following patch fixes abi_check failure:
