[Buildroot] [PATCH v3 0/7] glibc: bump to 2.26

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

This series bump glibc to the latest release and allow to remove all
patches required for the previous version! But glibc come with some
new issue that are hopefully already fixed in the 2.26.x stable branch.

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.

Backport a series related to bug 21930 and 22146.
Without them the float128 support break the C++ build for some
packages.

This third series is for testing and review.
Let's hope that glibc 2.26.1 will be released soon :)

Best regards,
Romain
