drivers/built-in.o: In function `vexpress_reset_do.clone.0':
iio-trig-interrupt.c:(.text+0x1aff38): undefined reference to `__vexpress_config_func_get'
iio-trig-interrupt.c:(.text+0x1aff4c): undefined reference to `vexpress_config_write'

The filename above will be misleading due to the way the toolchain works.
