Ed25519 signing no longer adds useful friction. Drop libonion_integrity, tools/elf_sign, and the XOR integrity toasts so builds no longer sign daemon.elf.

# OnionHEN shared CMake helpers.

# Every module under source/ used to repeat the same prologue: language
|
|
# standards, the PS5 SDK header paths, a clang check, the cross-compile target
|
|
# triple, the output directories, and an objcopy strip step. That was 17 copies
|
|
# of the triple, 11 of the IS_SUBPROJECT dance, 9 clang checks and 6 strip
|
|
# blocks — all of which had to be kept in sync by hand.
|
|
#
|
|
# Modules now call:
|
|
# onion_module_prologue() # standards + SDK includes + clang check
|
|
# onion_output_dirs() # bin/ and lib/ layout
|
|
# onion_strip_debug(<target>) # post-build objcopy (ELF targets only)
|
|
#
|
|
# Compiler flags stay per-module: the modules genuinely differ (libhijacker
|
|
# builds -O3 -fno-exceptions, shellui adds -pedantic, libNidResolver is
|
|
# -nostdlib). ONION_PS5_TARGET_FLAGS holds only the part that is identical
|
|
# everywhere, so a module composes it with its own flags rather than retyping
|
|
# the triple.
