Hello,
There was a build failure with gcc-12: missing reference to
pthread_once. This is due to a mismatch in glibc concerning where
pthread functions are, gcc is assuming all ports behave the same. I'm
currently trying the attached patch which should fix things.

libstdc++: Introduce GNU/Hurd-specific libstdc++ os-defines.h
This is notably needed because in glibc 2.34, the move of pthread functions
into libc.so happened for Linux only, not GNU/Hurd.
The pthread_self() function can also always be used fine as it is.
