Out binutils version adds the reloc sections by default, but NSIS does
not work with them.
So, we need to pass a flag to disable them, otherwise users with
mandatory ASLR turned on will not be able to install Tor Browser.

The --enable-tor-browser-update and --enable-verify-mar options are
already set by default in tor-browser.git.

The wasi-sandbox project was not reproducible, because libc.a was
filled in a non-deterministic order.
Its Makefile contains some wildcards, but adding a sort to them was not
enough to build libc.a deterministically.

After fixing this problem, Firefox build issue disappears, too.
