    lto: Also copy .note.gnu.property section
    
    When generating the separate file with LTO debug sections, we should
    also copy .note.gnu.property section.
    
    	PR lto/93966
    	* simple-object.c (handle_lto_debug_sections): Also copy
    	.note.gnu.property section.
    
    (cherry picked from commit 577350603a657590c4b54a4a966cb49497e2514c)
