OK. I'm about to start a rebuild of all my toolchains + Qemu tests with
glibc 2.26 (and gcc 7.x, binutils 2.29, etc, i.e the bleeding edge
toolchains).
FYI: the two gcc patches that you needed to build glibc 2.26 are no
longer needed once you bump gcc to 7.2.0, which I have done for this
toolchain rebuild. I'll send the gcc 7.2.0 bump patch once all
toolchains have been rebuilt.
I'll let you know the result.
Best regards,
Thomas
