I enhanced the error checking, and the rdepends varflag in your example
indeed isn't valid. ":do_populate_sysroot" got appended twice to the
recipe name. That error got ignored silently earlier.

populate_sdk_ext.bbclass appends ":do_populate_sysroot" when setting
do_sdk_depends[rdepends], so you should use just:

   SDK_TARGETS += "ti-cgt-pru-native"
