SEND_STDERR_DEBUG does nothing if __SUPPORT_LD_DEBUG_EARLY__ is not defined
thus causing a warning.

Fixes this:

In file included from ldso/ldso/ldso.c:86:0:
ldso/ldso/dl-startup.c: In function '_dl_start':
ldso/ldso/dl-startup.c:313:13: warning: variable 'strtab' set but not used [-Wunused-but-set-variable]
       char *strtab;
             ^~~~~~
