[Buildroot] [PATCH v3 1/2] libnspr: Add dependency on !BR2_xtensa and !BR2_bfin

[Baruch Siach]

From: Chris Zankel <chris at zankel.net>

Xtensa is not yet supported in libnspr. Also add dependencies to libnss,
which requires libnspr, and ecryptfs-utils, which requires libnss.

Fixes (xtensa)
http://autobuild.buildroot.net/results/14b/14ba6426edbffa100de924aa69157b3f59368ff2/

Fixes (blackfin)
http://autobuild.buildroot.net/results/dd3/dd353703ed94cec48cd126d80cd2f1b039811be4/

[baruch: fix summary, add autobuild reference, add comment dependency,
 add blackfin]
