commit 088de7d0091bdfac4b702ab2060289affc85d6a4
Author: Joseph Myers <joseph@codesourcery.com>

    Clean up build-many-glibcs.py libcilkrts disabling.
    
    The disabling of libcilkrts in build-many-glibcs.py has some
    peculiarities.  It's only for the final GCC build, not the initial
    bootstrap one, whereas normally anything disabled for the final build
    should be disabled for the bootstrap one as well.  And it's only for
    Hurd, when it's more natural by analogy with the libsanitizer
    disabling to disable this library unconditionally, not only for
    targets where it's known to break.  This patch cleans up that
    disabling accordingly, adding a comment so it's obvious it can be
    removed once GCC 7 is too old to build glibc.
    
    	* scripts/build-many-glibcs.py (Config.build_gcc): Use
    	--disable-libcilkrts unconditionally, not just for the final GCC
    	build for Hurd.
