Follow-up Comment #3, bug #28921 (project avr-libc):

The point the trampoline is generated and used is where the linker tries to
assign an address bigger than 16 bit to a 16 bit symbol. It doesn't matter
what type this symbol had in the C code.
Example:
void SomeFunc (void) {
}
...
uint16_t adr = (uint16_t)SomeFunc;
If SomeFunc is located above 128k, then there will be a trampoline for it and
adr will contain the word address of that trampoline.
