nss: Fix build when using clang toolchain

Browse Source 
When using clang cross compiler, nss make system adds
some clang specific options e.g. Qunused-options to CFLAGS
which is fine for cross/target compile but some portions e.g.
nsinstall is build natively so it uses NATIVE_CC to compile this
utility, its is set to BUILD_CC rightly but when using clang for CC
and gcc for BUILD_CC, nss build system is confused because its
trying to use the computed set of warnings for both native and cross
compile and they may not match between clang and gcc. So here we
explicitly use clang for NATIVE_CC when TOOLCHAIN is clang
