Static Compilation on libboost 1.71 fails

[polarisfm]

Static compilation on newer versions of libboost fails, notably libboost 1.71 which ships with Ubuntu 20.04 and Debian 11.

This was tested on Ubuntu 20.04 and Debian 11 on amd64 and arm64 machines. The issue isn't related to the compiler used and is reproducible using gcc 9, gcc 10, clang 10, and clang 11.

Currently you can workaround this issue by using debootstrap to spin up an older distribution, then chroot into it, but that isn't a great long-term fix.

cmake errors (Debian 11 arm64):
