I am trying to update a riscv32 (ilp32) chroot, which so far used glibc-2.32
plus the rv32 patchset backported from master branch.

The build of glibc-2.33 fails with undefined symbols:

The environment is somewhat experimental (a mostly functional rv32 qemu-user
chroot). More eyes on the problem would be appreciated though.

--- Comment #1 from Andreas Schwab <schwab@linux-m68k.org> ---
2.33 is the first version with official support for riscv32, so you need to
rebootstrap your system.

Ack, thanks. 

Let's see how this goes...
