kernel: disable THREAD_USERSPACE_LOCAL_DATA if LIBC_ERRNO
Browse files Browse the repository at this point in the history 
Thread userspace local data is to be used with storing errno per
thread without thread local storage support. However, if the C
library has native errno support, there is no need to enable
thread userspace local data to store errno per thread. Therefore,
amend the default for CONFIG_THREAD_USERSPACE_LOCAL_DATA so that
it is not enabled if the C library has native errno support.
