instead of rejecting the default stop position. [#2801]

### Packages & Distribution
- Lower the Linux glibc floor from 2.31 to 2.28 so released binaries run on
OracleLinux 8 / RHEL 8 (and Debian 10, Ubuntu 18.04+). The target is set via
Zig's `-target <arch>-linux-gnu.2.28`, so the floor is independent of the build
host's glibc; the existing `make ldd` check verifies the maximum required GLIBC
symbol stays within the target for `acton`, `lsp-server-acton`, and `actondb`.
- Change x86_64 Linux builds from statically linked GNU libc to dynamically
linked GNU libc while keeping other libraries statically linked. [#2774,
#2781]
