The sysconf() function is implemented compile-time constant via macros. This is the option
with the least overhead. The downside is that sysconf() is not an addressable function.
config POSIX_SYSCONF_IMPL_FULL
bool "Full"
help
The sysconf() function is implemented as a large integer-integer array. The advantage if this
option is that all sysconf() options can be queried and that the sysconf() symbol is
addressable.
