[Buildroot] [PATCH v2 00/11] glibc: bump to 2.26

[Romain Naour <romain.naour@gmail.com>]

This series bump glibc to the latest release and allow to remove all
local patches! Sadly this new release come with some C++ regressions
or changes needed in packages.

While testing this new version, some build issues has been dicovered.
Two gcc patch are needed to build a toolchain with older compiler
(gcc 4.9 to 6.4), gcc 7.2 contain already the fix.

Another C++ namespace change trigger a build issue when the code
contain a workaround for math functions:

mesa3d:
"using std::fpclassify;"

https://github.com/mesa3d/mesa/blob/master/include/c99_math.h#L197

jsoncpp:
"#define isfinite std::isfinite"

It's not easy to catch all packages affected by this issue before
bumping glibc. So here is the v2 for testing and review containing
additional fixes.

This series is rebased on master after 2017.08 release.

Best regards,
Romain
