While BSD make support both $() and ${} around variables, the NetBSD
source tree uses only ${} by convention.
Imported software is left as is, and sometimes $() is used when the
containing Makefile/Makefile fragment is used both by GNU make and BSD
make, as it can happen for the tools, and other parts as well which are
compiled using the host make tool.

Please note that this information is for use by system services only!
The clock facility is not ready to be used directly by userland, and
thus, this kernel page extension is NOT part of the userland ABI.
For service programmers' convenience, change the prototype of the
getticks(3) to return the uptime clock value directly, since the call
can no longer fail.
Correct the sys_times(2) reply message to use the right field type
for the boot time.
Restructure the kernel internals a bit so as to have all the clock
stuff closer together.
