Avoid bogus warnings when configuring for Qt6

Recent versions of qmake complain loudly when the locale
does not explicitly specify the utf8 codeset. Specifically,
the configure script exports LC_ALL=C and that implies the
ascii codeset. Previously, this was silently changed to utf8,
whereas now we get a warning for each qmake invocation.
So, explicitly set utf8 before calling qmake.
