It is described on INSTALL file:

408 Installing the C Library
409 ========================
410
[...]
437    You can install the GNU C Library somewhere other than where you
438 configured it to go by setting the 'DESTDIR' GNU standard make variable
439 on the command line for 'make install'.  The value of this variable is
440 prepended to all the paths for installation.  This is useful when
441 setting up a chroot environment or preparing a binary distribution.  The
442 directory should be specified with an absolute file name.  Installing
443 with the 'prefix' and 'exec_prefix' GNU standard make variables set is
444 not supported.
