  A glibc master build with --enable-nss-crypt using the NSS 
crypto libraries fails during make check with the following error:

<command-line>:0:0: error: "USE_CRYPT" redefined [-Werror]
<command-line>:0:0: note: this is the location of the previous 
definition

This is caused by commit 36975e8e7ea227f7006abdc722ecfefe2079429b 
by H.J. Lu which replaces all = with +=. The fix is to undefine 
USE_CRYPT before defining it to zero.

Committed as an obvious fix. Fixes the build issue on x86_64 with
no regressions.

	* elf/Makefile [$(nss-crypt)$(static-nss-crypt) == yesno]
	(CFLAGS-tst-linkall-static.c): Undefine USE_CRYPT first.
