New AArch64 GAS testsuite failure for CSSC

[Nick Clifton]

Hi Andre,

   I am seeing a new testsuite failure in the GAS testsuite for AArch64
   targets.  There appear to be two problems.  For a toolchain configured
   as aarch64-linux-gnu it seems that the regexps do not match.  (There
   appears to be some extra text in gas/testsuite/gas/aarch64/cssc.d that
   is not present in the disassembler output).

   Secondly, for a toolchain configured as aarch64_be-linux-gnu the test
   source file does not assemble at all. :-(

   Please could you fix these problems ?

Cheers
   Nick
