#
# This function handles three separate target lists:
#   THEROCK_AMDGPU_TARGETS: Per-architecture targets for architecture-specific builds
#   THEROCK_DIST_AMDGPU_TARGETS: Distribution targets (used by runtime components
#     that embed device code for user-selected architectures). Controls what is
#     reported in dist_info.json and consumed by downstream tools (e.g. PyTorch
#     via `rocm-sdk targets`). Defaults to THEROCK_AMDGPU_FAMILIES.
#   THEROCK_TEST_AMDGPU_TARGETS: Targets for test artifacts marked TARGET_NEUTRAL.
#     Defaults to ALL available (registered) targets so that a single _generic
#     test artifact works on any architecture, making upload races in classic CI
#     harmless. Does NOT affect dist_info.json.
#
# In multi-arch CI, generic stages (those building architecture-independent code)
# may have no per-arch targets but still need dist targets. In this case,
# THEROCK_AMDGPU_TARGETS is set to a sentinel value "THEROCK_AMDGPU_TARGETS-NOTFOUND"
