One I’ve had hanging around in my local trees for a long time.

We have been emitting two section switches in the Darwin's
file end function by outputting the asm directly.  This means that
varasm’s tracking of the section switched  is not updated
which could matter if we elect to reorder some of the file
end operations in support of LTO actions.

tested on powerpc-darwin9, x86_64-darwin18
applied to mainline

        * config/darwin.c (darwin_file_end): Use switch_to_section ()
        instead of direct output of the asm.
