Use support of a new platform in libtinymail

[mehdi bayarassou <mehdibayarassou gmail com>]

Hello,
We want to add a new platform support in libtinymail.
We generated the files concerning account store, platform factory and device type. After creating pc.in files as well as makefile.am we added new lines to support our platform in the configure.ac we have an error while executing ./autogen. this error is related to AM_CONDITIONAL.
Are we forgetting a step or something?
can someone help us please.
Thanks.
