Please do not add libsys.so to the ABI. Right now it is an implementation
detail of libthr and libc, and
That's probably worth a shot. Static linking will work anyway because
libc.a in effect embeds libsys to retain compatability.

Can't we just add libsys.so to the /usr/lib/libc.so linker script? That would
work for everything except static linking?

TL;DR: you can work around this by adding -lsys to the link line and I
aim to improve the situation soon.
The sanitizers reach somewhat questionably into libc internals that are
exported to allow rtld to update them. I was unable to find an solution
that didn't break this and I felt that fixing
[Brooks' activity related to commit 99ea67573164637d633e8051eb0a5d52f1f9488e
looks likely for what changed the status: "lib{c,sys}: move auxargs more
firmly into libsys".]
