   If 1, then an errno global variable hidden in ld.so will work right with
   all the errno-using libc code compiled for ld.so, and there is never a
   need to share the errno location with libc.  This is appropriate only if
   all the libc functions that ld.so uses are called without PLT and always
   get the versions linked into ld.so rather than the libc ones.  */
