But 2.26 version introduced quite a few regressions on x86, x86_64 and
powerpc64le when float128 support was added. All these issues are now
fixed in the glibc 2.26 stable branch.

Backport patches from glibc 2.26 stable branch related to bug 21930.
Take all patches listed in this bug report in order to have all fix
for this issue [1] [2].

Fixes gnuradio build:
[...]/sysroot/usr/include/boost/functional/hash/detail/hash_float.hpp: In function ‘std::size_t boost::hash_detail::float_hash_value(T)’:
[...]/sysroot/usr/include/boost/functional/hash/detail/hash_float.hpp:210:21: error: expected primary-expression before ‘float’
             switch (fpclassify(v))
                     ^

                     ^

             switch (fpclassify(v))
                     ^
[...]/sysroot/usr/include/boost/functional/hash/detail/hash_float.hpp:210:21: error: ‘_Float128’ is not a class or namespace
             switch (fpclassify(v))
                     ^

[...]/sysroot/usr/include/boost/functional/hash/detail/hash_float.hpp:210:21: error: ‘_Generic’ was not declared in this scope
             switch (fpclassify(v))
                     ^

Also backport fix for glibc bug 22146.
Without this patch some C++ applications (jsoncpp, mesa3d and kodi) fail
to build due to an issue while building the toolchain.

A test in the libstdc++ configure script fail when -Os and float128 are
used.

See the bug report for details [3].

Subject: [PATCH] Fix the C++ version of issignaling when __NO_LONG_DOUBLE_MATH
is defined
When __NO_LONG_DOUBLE_MATH is defined, __issignalingl is not available,
thus issignaling with long double argument should call __issignaling,
instead.
Tested for powerpc64le.
* math/math.h [defined __cplusplus] (issignaling): In the long
double case, call __issignalingl only if __NO_LONG_DOUBLE_MATH
is not defined. Call __issignaling, otherwise.
(cherry picked from commit 3d7b66f66cb223e899a7ebc0f4c20f13e711c9e0)
