  Trying to link something statically against glibc is a gamble; even
if it appears to work it's not guaranteed that it will run correctly,
depending on the amount of ifuncs and dlopens that have been pulled in.
Unless it builds out of the box, it's generally not worth spending
effort in trying to make it work. Stick to dynamic linking with glibc;
if you want static binaries, switch to another libc, such as musl.
