LLVM considers global variables marked as externals to be defined within the module if it is initialized (including to an undef). Other external globals are considered as being defined externally and imported into the current translation unit. Lowering of MLIR Global Ops does not properly propagate undefined initializers, resulting in a global which is expected to be defined within the current TU, not being defined.

[flang] Add default implementation for SYSTEM_CLOCK
Add an implementation for the runtime functions related to SYSTEM_CLOCK.
As with CPU_TIME, this is based on std::clock(), which should be
available everywhere, but it is highly recommended to add
platform-specific implementations for systems where std::clock() behaves
poorly (e.g. POSIX).
The documentation for std::clock() doesn't specify a maximum value and
in fact wrap around behaviour is non-conforming. Therefore, this
implementation of SYSTEM_CLOCK is not guaranteed to wrap around either,
and after std::clock reaches its maximum value we will likely just
return failure rather than wrap around. If this happens often on your
system, please add a new platform-specific implementation.
We define COUNT_MAX as either the maximum value that can be stored in
a std::clock_t or in a 64-bit integer (whichever is smaller), and
COUNT_RATE as CLOCKS_PER_SEC. For POSIX systems, the value of
CLOCKS_PER_SEC is hardcoded to 10^6 and irrelevant for the values
returned by std::clock.
