This is most likely due to the variable gdb_cv_cxx_std_thread being empty. See, we get the
same error message if we do this with bash:
bash$ test = yes
bash: test: =: unary operator expected
We either need to
(1) make sure gdb_cv_cxx_std_thread is set to something, regardless of the code path taken
(2) wrap $db_cv_cxx_std_thread in quotes
Even if we do (1), it's good practice to do (2), in case the variable has spaces in it.
That code is in gdbsupport/common.m4.
