Description of problem:
1. Doing custom kernel build using make xconfig generates on save:

ERROR - Attempting to write value for unconfigured variable (CONFIG_ZLIB_INFLATE).
ERROR - Attempting to write value for unconfigured variable (CONFIG_ZLIB_DEFLATE).

2. After make dep, make clean, then make bzImage generates the following:
