configuration:
[general]
name = minimal
extends = default.ini


[modules]
crypto_openssl = off
netinet6 = off
fdt = off
dev_nic_fxp = off
dev_nic_re = off
dev_nic_smc = off
dev_usb = off
dev_usb_controller = off
dev_usb_controller_bbb = off
dev_usb_input = off
dev_usb_net = off
dev_usb_quirk = off
dev_usb_serial = off
dev_usb_storage = off
tests = off
usr_sbin_tcpdump = off



I searched the source files, thers is no any reference about intr_event_suspend_handler() and intr_event_resume_handler()
So I just move #endif from line:902  to line:946 to avoid these errors.

What is the build log showing the link error? How did you configure libbsd?
