[Bug 1915275] Re: mysql-8.0 regressed on riscv64 due to new glibc

[Bryce Harrington]

Excellent work tracking this down Christian; I appreciated being able to
follow along with your detailed analysis.

Marking this not a php7.4 bug specifically, but will make sure php7.4
rebuilds once this is in.

** Changed in: php7.4 (Ubuntu)
       Status: New => Invalid

Bug description:
  Hello, looks like mysql-8.0 can't run anymore its testsuite on riscv64, due to a probable bug in glibc.
  See e.g.
  https://launchpad.net/ubuntu/+source/mysql-8.0/8.0.23-1ubuntu1/+build/20983618

  I'm currently building on bileto with release pocket, to have a fast migration, because this is blocking some reverse-dependencies such as boinc from building correctly on riscv64.
