When generating xcoff_%.c, the last command is a sed command. In case of a
sed failure, this will leave an incomplete file, which will appear as up to
date to make, so consequently it will not be regenerated. Fix this by
sedding into a temporary file instead.
Also, use $< to access the prerequisite xcoff.c, instead of spelling out the

This is pretty unlikely in real code, but similar to Arm, the AArch64
ABI has a bug with the handling of 128-bit bit-fields, where if the
bit-field dominates the overall alignment the back-end code may end up
passing the argument correctly. This is a regression that started in
gcc-6 when the ABI support code was updated to support overaligned
types. The fix is very similar in concept to the Arm fix. 128-bit
bit-fields are fortunately extremely rare, so I'd be very surprised if
anyone has been bitten by this.
