# Since the "bfd/hosts" directory is shared by the bfd, opcodes, and
# binutils directories (at least), the index to it is also shared.
# This is that index. Each configure.in file should source this file
# in its per-host part.

-#
-# Note that these entries cannot be fully alphabetical. Don't try.
-# The order of matching is critical when multiple lines could match.
