[ptxdist] [PATCH v2] confdata.c: (Re-)add warning about unassigned symbols.

[Christian Melki <christian.melki@t2data.com>]

The Linux kconfig has removed a warning regarding unassigned symbols.
Commit f072181e6403b0fe2e2aa800a005497b748fd284,
kconfig: drop the ""trying to assign nonexistent symbol" warning.

This warning actually helps detecting symbol renames which are lost in
translation which in turn is helpful when doing oldconfigs etc.
