ldbl-128ibm-compat: Add error.h functions 

Use the recently added, internal functions, __error_at_line_internal and
__error_internal, to provide error.h functions that can take long double
arguments with IEEE binary128 format on platforms where long double can
also take double format or some non-IEEE format (currently, this means
powerpc64le).

Tested for powerpc64le.
