    libgcc: aarch64: Do not use .previous after build attributes
    
    .aeabi_subsection selects the current AArch64 build-attribute
    subsection, not the current ELF section.  The following .previous
    therefore does not return from the build-attribute subsection.  In
    aarch64-asm.h it instead switches back to .note.GNU-stack, which was the
    previous ELF section after emitting the non-executable stack note.
    
    Remove the .previous from the build-attribute marking path.  Keep it in
    the GNU_PROPERTY path, where it matches the explicit switch to
    .note.gnu.property.
    
    libgcc/ChangeLog:
    
            * config/aarch64/aarch64-asm.h (FEATURE_1_AND_MARK): Do not emit
            .previous after AArch64 build attributes.
