How about this alternative wording of the comment:

  # WARNING: Invoking the assembler directly is problematic.
  # For targets which support multilibs a compile time switch is used
  # to select the appropriate multilibs.  This switch may not be same
  # as the switch that the compiler will pass on to the assembler.  For
  # example if big-endian and little-endian multilibs are supported
  # the compiler options will probably be -mbig-endian and -mlittle-endian
  # but, for historical reasons, the assembler options are probably -EB
  # and -EL.
  #
  # Since these tests are supposed to be able to be run for targets for
  # which there is no compiler we cannot just invoke a compiler driver
  # program (eg 'gcc') to handle this translation for us.  For now we
  # just hard code the endian translation and hope that there are no
  # others that are needed.

Cheers
