[Buildroot] [PATCH 0/7] glibc: bump to 2.26

[Romain Naour]

This series bump glibc to the latest release and allow to remove all
local patches!

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 v1 for testing and review.

This series is rebased on master in order to have gcc 7.2 from
2017.08-rc3.
