it doesn't work like that here, I've just added following into check-lxdialog.sh:

  echo "$(command -v pkg-config)" > $TOPDIR/meh.log

and meh.log contains /usr/bin/pkg-config after kernel_menuconfig run.

if I understand it correctly this global exports are not welcome.

similar approach was already suggested[1] by Thomas originally and was considered
brittle (and I agreed with that), so I've reworked it to current version.
