    binutils221: final solution to start/stop label generation
    
    During discussion on binutils mail list about preserving the
    __start_* and __stop_* section labels, Dimitry Andric indicated that
    FreeBSD had the same exact issue when they recently upgraded to
    binutils 2.17.50.  The solution they chose was to declare these section
    labels as global symbols, and the stock version of ld will retain them.
    
    This commit implements the FreeBSD solution.  Besides the obvious
    benefit of having minimalist shared objects, it also "fixes" binutils
    2.20 which, until this commit, failed to generate the start/stop section
    labels.
    
    Commit f070647cc5317c4924be4dd60563fc39c18094cf has been reverted to
    convert binutils 2.21 to a completely stock ld.  Some whitespace cleanup
    of linker_set.h was done while modifying __MAKE_SET macro.
