Subject: [PATCH 0/1] Fix kconfig core dumps running make oldconfig

When running make oldconfig cirtain configurations kconfig will coredump.
This is triggered by an issue calculating the length of the result of
expanding symbol values containing variables.  This prevents builds on
these configs.

This bug was exposed by the commit below which _correctly_ fixed the
usage of realloc():
