libffi: Pass --build and --host to configure script
Without this, building `libffi` would do something horrible when
natively targeting `armv5tel-linux` on an `aarch64-linux` machine using the
32-bit compatibility sub-mode:
```
$ nix-build --system armv5tel-linux -A libffi --check
[...]
checking build system type... aarch64-unknown-linux-gnu
checking host system type... aarch64-unknown-linux-gnu
checking target system type... aarch64-unknown-linux-gnu
[...]
$ file result/lib/libffi.so.8.1.0
result/lib/libffi.so.8.1.0: ELF 32-bit LSB shared object, ARM, EABI5 version 1 (SYSV), dynamically linked, not stripped
$ nm result/lib/libffi.so.8.1.0 | grep ffi_call
U ffi_call
```
Correct arch-specific code wouldn't be built at all, with the resulting binary subtly broken.
