commit e1490cde2954ba65a06bd147d38df675c167dfea
Author: Matthieu Longo <matthieu.longo@arm.com>

    ld tests for AArch64-specific merge coverage for AEABI Build Attributes
    
    Test cases:
    - coverage of required subsection 'aeabi_pauthabi'.
    - coverage for BTI, PAC, GCS used along GNU properties.
    - warn on unknown attributes, and prune them from output.
