Follow-up to 958a8ae7 because the 0.10.0 [release notes] also
request `--enable-bcm2835gpio` for builds that support Raspberry Pi:

> 7.  Please add --enable-sysfsgpio for all targets running Linux, the
> kernel (esp. useful for SBCs), additionally for builds that support
> RaspberryPi, please add --enable-bcm2835gpio

`--enable-bcm2835gpio` is ignored when building on non-ARM architectures.
This configuration is also consistent with the [Debian packaging].
