Maybe add a small comment above the config option to state that this is
included from the linux-tools infra, rather than from the usual
package/Config.in, to avoid confusing developpers later on...

So you dropped the dependency on !static. Does that mean you were able
to test it with a static build?
It also required libudev, so you have to depend on BR2_PACKAGE_HAS_UDEV.
It needs usb.ids from usbutils, so you also need to select it:
# This file is included from linux-tools, not from the usual
# package/Config.in location, because it is a linux tools, but uses
# the autotool infra
config BR2_PACKAGE_USBIP
bool "usbip"
depends on BR2_PACKAGE_HAS_UDEV
depends on BR2_TOOLCHAIN_HAS_THREADS # usbutils <- libusb
select BR2_PACKAGE_USBUTILS
comment "usbip needs udev /dev management and toolchain w/ threads"
depends on !BR2_PACKAGE_HAS_UDEV \
|| !BR2_TOOLCHAIN_HAS_THREADS
It also has optional support for libwrap, which we do not have in
Buildroot. See below...

Incorrect header. ;-)

Since it uses udev, you also have to depend on it:
USBIP_PATCH_DEPENDENCIES = linux
USBIP_DEPENDENCIES = udev
(Just to show that you have both types of dependencies.)
Also, it can use libwrap, which we do not have in Buildroot, so you
may want to forcibly disable it:
USBIP_CONF_OPTS = --without-tcp-wrappers

No need to use [[...]], you can simply use [...] here.

I think you will want to really mimick the rsync rule we use elsewhere:
rsync -au --chmod=u=rwX,go=rX $(RSYNC_VCS_EXCLUSIONS) $(USBIP_SRC_DIR)/ $(@D)
