From: Rajalakshmi Srinivasaraghavan <raji@linux.vnet.ibm.com>
The API doesn't change, i.e. compilers using a long double format compatible
with the IEEE 128-bit extended precision format are redirected from *l
functions to __*ieee128 symbols using the same mechanism already
used with -mlong-double-64 for complex math functions.
2018-06-19 Rajalakshmi Srinivasaraghavan <raji@linux.vnet.ibm.com>
* math/complex.h [__HAVE_DISTINCT_FLOAT128 &&
!__HAVE_FLOAT128_UNLIKE_LDBL]: Redirect long double functions
to __*ieee128.
