while trying to follow up on bugid 26137 I had 31 failed tests from 2.32

On a Debian i686 server running Debian sid and with a custom built Linux
kernel 5.8.8 I was able to checkout and configure the glibc 2.32 sources
with no problem at all :

The compile seemed to complete fine however the testsuite was somewhat
less than fine :

Curious what the next steps are to follow up on these failures? Is it
normal to have a bunch of failures similar to bootstrapping gcc ?
