OK, so upstream glibc is already fixed which is good, but there is at
least one glibc release with the bug, and some trees like
github.com/riscv/riscv-gnu-toolchain that have the broken glibc
sources.  I can deal with that problem though.  We will probably
upgrade glibc when we upgrade gcc anyways.
