Yes, that will work. If the DEPENDS change implies some different configuration 
I'd recommend being explicit about it as well e.g. via EXTRA_OECONF or 
whatever is appropriate; this is particularly important for the case where the 
extra dependency is not included and the configure script for the application 
would auto-detect the presence of the additional dependency in the absence of 
an explicit configure option.

Also, ideally these machine-specific bits should live in a bbappend within the 
BSP for that machine, thus keeping the recipe itself more or less generic.

Cheers,
Paul
