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
file name once more.

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.

Currently, when running a libbacktrace testcase t with .gnu_debuglink to
t.debug, and t.debug having a .gnu_debugaltlink to t.alt.debug, a segfault
is triggered when calling strrchr with a NULL string from
elf_find_debugfile_by_debuglink. The NULL string originates from the elf_add
called for the .gnu_debugaltlink, which uses NULL as filename argument.
Fix this by using "" as filename argument instead.
