kbuild: fix false positive warning/error about missing libelf
[ Upstream commit ef7cfd00b2caf6edeb7f169682b64be2d0a798cf ]
For the same reason as commit 25896d073d8a ("x86/build: Fix compiler
support check for CONFIG_RETPOLINE"), you cannot put this $(error ...)
into the parse stage of the top Makefile.
Perhaps I'd propose a more sophisticated solution later, but this is
the best I can do for now.
