Unable to create ExternalSymbols in non-PE views

Version and Platform (required):

• Binary Ninja Version: 4.1.5403-dev Personal (45205530)
• OS: Ubuntu Linux
• OS Version: 22.04
• CPU Architecture: x64

Bug Description:
When in a non-PE view, symbols of type ExternalSymbol will not get created.

Steps To Reproduce:
Please provide all steps required to reproduce the behavior:

1. In an ELF view or empty file create a section with SectionSemantics.ExternalSectionSemantics
2. Define a symbol in that section with SymbolType.ExternalSymbol
3. The log will output an analysis update, but the symbol does not render in the view. It seems like it doesn't get created in any way.

Expected Behavior:
I would expect an ExternalSymbol to be created and rendered in the section. If doing the above steps on a PE binary, you get the expected results.

Additional Information:
Doing these steps through the API or GUI gives the same results. This is also the same result if created with define_auto_symbol or define_auto_symbol_and_var_or_function

I maintain binaryninja-xbe which loads PE-like binaries

Reproduce the issue in an ELF view or empty file by creating an external section and defining an ExternalSymbol through the API or GUI. Start with define_auto_symbol and define_auto_symbol_and_var_or_function, then compare non-PE behavior with a PE view. Done means the ExternalSymbol is created and rendered in the section for non-PE views.
