I would create src/lib/libkse/{libpthread,libthread}, and have
src/lib/libkse/Makefile.inc0 that contains everything to build the libs
except for the -D's and the lib name. Have
src/lib/libkse/{libpthread,libthread}/Makefile include ../Makefile.inc0
and define the missing parts.
The BSD Makefile framework really does depend and expect separate
directories for each product.
