New arch support: PowerPC 32-bit, tested on v5.0+ kernels.

Improvements:

  • Improve kconfig dependency checking logic for better warning/error messages.
  • PowerPC PPC64: improve esoteric fast switch_endian syscall detection.
  • Better (narrower) emoji spacing in HTML output.

Bug fixes:

  • Correctly report delete_module depending on CONFIG_MODULE_UNLOAD=y.
  • Fix incorrectly handled shared syscall table in x86-64 x32 ABI resulting in duplicated and unwanted entries in the output for kernels older than v5.4.
  • Fix chance of building kernels without memfd_create, memfd_secret, delete_module (and possibly others) by always enabling MEMFD_CREATE, MODULE_UNLOAD, NET and SECRETMEM when available.
  • Fix wrong handling of relative --kdir path (e.g., .) in some cases.
  • Fix missed detection of non-implemented syscalls pointing to kernel/sys_ni.c when DWARF debug info contains relative paths.
  • x86 x32: fix some x64 syscalls reported twice because both the x64 number and the historycally misnumbered x32 numbers (512-547) were being considered valid.

Internal changes:

  • Ignore sound/ and user/ dirs to speed up grepping syscall definitions.
  • Implement some basic unit tests for powerpc dummy/esoteric syscall detection.
