weird, this compiled just fine here with allmodconfig on AArch64.

/me goes check. Oh, I see what's happening, hsotg->test_mode is only
compiled on Peripheral-only and Dual-role builds. I'm assuming this was
a Host-only build. Then the problem triggers because drd.o is
unconditionally added to the binary.

dwc2-y					:= core.o core_intr.o platform.o drd.o

Is this an old problem or was it triggered by $subject?
