Synopsis: When casting spell "linux" without loadable modules support, it exits with the following error:

The present kernel configuration has modules disabled.
Type 'make config' and enable loadable module support.
Then build a kernel with module support enabled.

make: *** [Makefile:1383: modules] Error 1

How to reproduce: 'cast -r linux' with "CONFIG_MODULES=n".

How to fix: In 'BUILD': check for "CONFIG_MODULES=y" before calling 'make modules'. Diff:
