In fact, backup in the output and look at the flags used to build libpq.
Are they correct?  If they are, you shouldn't need any additional flags
when building initdb because initdb doesn't call any threaded functions,
_except_ if you have that limitation that a libpq using threads requries
a thread flag for everything that calls libpq.

Please report back.
