I had done a "make menuconfig", turned on WCHAR support, done "make clean",
then "make", and ended up with a no-wchar build, confirmed by doing "make
uclibc-menuconfig" and noting that the WCHAR option was not enabled.

Apparently "make clean" wasn't enough to clean things out properly.  I don't
have a directory "output", but I re-extracted buildroot from the tarball and
rebuild with BR2_USE_WCHAR on, and it seems to have worked.  Thanks!

It would be really nice to have a section in the buildroot documentation
describing what you need to do when rebuilding after changing various settings,
for example:
  - After changing a toolchain option.
  - After changing a uclibc or busybox option.  (And when do the uclibc or
busybox .configs get clobbered?)
  - After enabling or disabling a package.
