not really.
if you obtained puredata from the raspbian repositories (as opposed to 
the Debian repositories), or compiled it yourself (without paying 
careful attention, using the raspbian provided toolchain - iirc), you 
would get a Pd-armv6.
now Pd reports to deken which architecture it supports, but the code is 
just some compile-time #ifdef magic, and doesn't actually query the CPU 
capabilities.
the net result of this is that Pd tells deken that it supports armv6, 
but not armv7 (or - heaven forbid - armv8) - so that's why you can only 
see arvm6-externals (unless you manually configure deken to use 
"Linux-armv7-32")

as said before: somebody should do some benchmarking how much gain there 
is for armv7 with respect to armv8.
