hwclock: add get/set parameters option

2023-07-12T14:27:49+00:00

In kernel 5.16 special ioctls were introduced to get/set RTC parameters.
Add option to get/set parameters into busybox version of hwclock.
Implementation is similar to the one already used in linux-utils hwclock
tool.

Example of parameter get use:
$ hwclock -g 2
The RTC parameter 0x2 is set to 0x2.
$ hwclock --param-get bsm
The RTC parameter 0x2 is set to 0x2.

Example of parameter set use:
$ hwclock -p 2=1
The RTC parameter 0x2 will be set to 0x1.
$ hwclock -p bsm=2
The RTC parameter 0x2 will be set to 0x2.

Fix non-Linux builds

2022-11-29T13:10:22+00:00

Various tools are Linuxish and should thus only attempted to build on
Linux only. Some features are also Linux-only.

Also, libresolv is used on all GNU platforms, notably GNU/Hurd and
GNU/kfreeBSD.
