This change deprecates the following Kconfig options * CONFIG_POSIX_ENV * CONFIG_POSIX_CONFSTR * CONFIG_POSIX_SYSCONF * CONFIG_POSIX_UNAME and instead groups them into a single Kconfig option that maps directly to the standard. Namely, CONFIG_POSIX_SINGLE_PROCESS. Signed-off-by: Chris Friedt <cfriedt@tenstorrent.com>

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.

|
|
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.
