elfcore: correct reference to CONFIG_UML
Commit 6e7b64b9dd6d ("elfcore: fix building with clang") introduces
special handling for two architectures, ia64 and User Mode Linux.
However, the wrong name, i.e., CONFIG_UM, for the intended Kconfig
symbol for User-Mode Linux was used.
Although the directory for User Mode Linux is ./arch/um; the Kconfig
symbol for this architecture is called CONFIG_UML.
Luckily, ./scripts/checkkconfigsymbols.py warns on non-existing configs:
UM
Referencing files: include/linux/elfcore.h
Similar symbols: UML, NUMA
Correct the name of the config to the intended one.
[akpm@linux-foundation.org: fix um/x86_64, per Catalin]
