Comment 0 for bug 1268685

fwts fails to build now on trusty because of changes in 1.14 requiring subdir-objects:

src/Makefile.am:21: warning: source file 'acpi/ac_adapter/ac_adapter.c' is in a subdirectory,
src/Makefile.am:21: but option 'subdir-objects' is disabled
automake: warning: possible forward-incompatibility.
automake: At least a source file is in a subdirectory, but the 'subdir-objects'
automake: automake option hasn't been enabled. For now, the corresponding output
automake: object file(s) will be placed in the top-level directory. However,
automake: this behaviour will change in future Automake versions: they will
automake: unconditionally cause object files to be placed in the same subdirectory
automake: of the corresponding sources.
automake: You are advised to start using 'subdir-objects' option throughout your
automake: project, to avoid future incompatibilities.
