#     ARM: Do not use NOCROSSREFS directive with ld.lld
#     
#     ld.lld does not support the NOCROSSREFS directive at the moment, which
#     breaks the build after commit b9baf5c8c5c3 ("ARM: Spectre-BHB
#     workaround"):
#     
#       ld.lld: error: ./arch/arm/kernel/vmlinux.lds:34: AT expected, but got NOCROSSREFS
#     
#     Support for this directive will eventually be implemented, at which
#     point a version check can be added. To avoid breaking the build in the
#     meantime, just define NOCROSSREFS to nothing when using ld.lld, with a
#     link to the issue for tracking.
