In extended-remote, when GDB connects the target, but target is not
running, the TSVs are not uploaded. When GDB attaches to a process,
the TSVs are not uploaded either. However, GDBserver has some
builtin or predefined TSV to upload, such as $trace_timestamp. This
bug causes $trace_timestamp is never uploaded.

This new script has one small snafoo, which prevented the $host_alias
and $target_alias from being expanded during the generation of the
version.c file. As a result, the version info yields:
This GDB was configured as "--host=$host_alias --target=$target_alias".
^^^^^^^^^^^ ^^^^^^^^^^^^^
This patch fixes this issue.
gdb/ChangeLog:
* common/create-version.sh: Fix expansion of $host_alias
and $target_alias in generation of HOST_NAME and TARGET_NAME
(resp.).
