[Replicant] [libsamsung-ipc] [PATCH 12/21] Autotools: Add --enable-samsung-ipc-device=[DEVICE] option

[Denis 'GNUtoo' Carikli]

In the Android.mk we have the following:
    ifneq ($(TARGET_DEVICE),)
    libsamsung_local_cflags += -DIPC_DEVICE_NAME=\"$(ipc_device_name)\"
    endif # ifneq ($(TARGET_DEVICE),)

This makes libsamsung-ipc assume that it runs on a specific device.

It can for instance be useful to test libsamsung-ipc on a device very
similar to one that is already supported, or during development.

The issue is that, with autotools and without this patch, this feature
is not easy to use as to force the i9300 device we would have to run
configure in this way:
    ./configure CFLAGS='-DIPC_DEVICE_NAME=\"i9300\"'
And we had no feedback that could indicate if it worked or not.

Note that even now, the only feedback we have is the output of
./configure because the autodetection of the device is done in
ipc_device_detect.

And ipc_device_detect is called by ipc_transport_client_create which
setups the ipc_client struct. And without a valid ipc_client struct,
we cannot use ipc_client_log, so we can't print in ipc_device_detect.
