ed79af77a4 config: PID_FILE_PATH required for FEATURE_CROND_SPECIAL_TIMES
When crond is built with FEATURE_CROND_SPECIAL_TIMES enabled, it creates
a file called 'crond.reboot' at CONFIG_PID_FILE_PATH, but if
FEATURE_PIDFILE is disabled, this will be an empty string and the file
will be created in the root directory, which is undesirable.

This commit makes PID_FILE_PATH depend on FEATURE_CROND_SPECIAL_TIMES as
well as FEATURE_PIDFILE so that you get sensible behaviour in crond when
FEATURE_PIDFILE is switched off.

ad27d44ebe runsv: Use 64 prefix syscall if we have to
Some 32-bit architectures no longer have the 32-bit time_t syscalls.
Instead they have suffixed syscalls that returns a 64-bit time_t. If
the architecture doesn't have the non-suffixed syscall and is using a
64-bit time_t let's use the suffixed syscall instead.

This fixes build issues when building for RISC-V 32-bit with 5.1+ kernel
headers.

If an architecture only supports the suffixed syscalls, but is still
using a 32-bit time_t report a compilation error. This avoids us have to
deal with converting between 64-bit and 32-bit values. There are
currently no architectures where this is the case.

d327c6b190 gzip: code shrink
Converted a few 16-bit variables and small arrays to 32-bit.

Stopped pulling desc->FOO members into temporary local variables
in gen_bitlen(): on register-starved arches, this is a loss,
temporaries go into stack slots.

Sprinkled a few "const" on pointer arguments.
