This patch needs a better description. This only describes *what* is
done, but not *why*. And the *why* is the most important, because the
*what* can trivially be seen by reading the patch :-)

Are you sure the NATIVE_CC and NATIVE_FLAGS options are needed? When
cross-compiling, I do understand the meaning of those options, but not
when building natively.

Same comment as for libnspr: there's more than x86-64 in the 64-bit
host architectures :)

Otherwise, looks good to me.

Thanks!
