[LTP] [PATCH v2 0/2] Fix generate_arch.sh and update syscalls to v7.3-rc5

[Andrea Cervesato]

This series addresses the regressions observed when regenerating syscall
tables for Linux v7.3-rc5 [1].

The previous attempt to update syscall tables dropped legacy syscalls
such as _sysctl and timerfd, and overwrote 31-bit s390 definitions with
64-bit s390x values due to kernel changes introduced in v6.19.

Patch 1 fixes generate_arch.sh:
- Includes table entries marked sys_ni_syscall and seeds names from
  generic headers and existing tables to retain legacy definitions
  like _sysctl and timerfd.
- Detects whether the 31-bit ABI is actually exposed by s390 headers
  instead of blindly overwriting s390.in with 64-bit definitions.
- Avoids compiler flag leaks across architectures.
- Fails immediately if compilation fails for any supported architecture.

Patch 2 updates the architecture input tables to Linux v7.3-rc5 using the
fixed generator. This provides clone3 on SPARC (resolving tst_clone
failures reported by Anders [2]), uprobe on x86_64, and new generic
syscalls (listns, rseq_slice_yield, fchroot) while preserving existing
legacy entries.
