Letting rtld access errno through TLS can not work at early stages since
TLS will not be initialized yet. When a private errno is not possible,
we thus have no other way than going through __errno_location.
* include/errno.h [IS_IN(rtld) && !RTLD_PRIVATE_ERRNO]: Do not use the
TLS declaration of errno.
