Linux: Add tables with system call numbers The new tables are currently only used for consistency checks with the installed kernel headers and the architecture-independent system call names table. They are based on Linux 5.4. The goal is to use these architecture-specific tables to ensure that system call wrappers are available irrespective of the version of the installed kernel headers. The tables are formatted in the form of C header files so that they can be used directly in an #include directive, without external preprocessing. (External preprocessing of a plain table file would introduce cross-subdirectory dependency issues.) However, the intent is that they can still be treated as tables and can be processed by simple tools. The irregular system call names on 32-bit arm add a complication. The <fixup-asm-unistd.h> header is introduced to work around that, and the system calls are listed under regular names in the <arch-syscall.h> file. A make target, update-syscalls-list, is added to patch the glibc sources with data from the current kernel headers.
