Thanks for that cleanup.  I pushed the attached commit
e9f8e3f109d57c119eaaa1e56378926f7f20863f "[GDB, Hurd] Fix build;
'target_waitstatus_to_string' call" to make it work.  ;-)

Subject: [PATCH] [GDB, Hurd] Fix build; 'target_waitstatus_to_string' call

Recent commit c29705b71a8ec966478c0dc4712194a95291c6de removed an incomplete
local implementation in favor of 'target_waitstatus_to_string' (thanks!), but
introduced a small typing error:
