[Qemu-devel] [PATCH 10/11] config: Add header file for device config options

[Alexander Graf <agraf@suse.de>]

So far we have C preprocessor defines for target and host config
options, but we're lacking any information on which devices are
available.

We do need that information at times though, for example in the
ahci patch where we need to call a legacy init function depending
on whether we have support compiled in or not.

So this patch makes all config-devices options available as header
file and includes it by default.
