Then there are lots of more or less obscure variables,
many obsolete or only for internal use.

By default (i.e., if this variable is not defined)
executables and prelinked
shared objects will honor base addresses of their dependent libraries
and (non-prelinked) position-independent executables (PIEs)
and other shared objects will not honor them.
If
.B LD_USE_LOAD_BIAS
is defined wit the value, both executables and PIEs
will honor the base addresses.
If
.B LD_USE_LOAD_BIAS
is defined with the value 0,
neither executables nor PIEs will honor the base addresses.
This variable is ignored by set-user-ID and set-group-ID programs.

.B LD_WARN
(ELF only)(glibc since 2.1.3)
If set to a non-empty string, warn about unresolved symbols.
