make includes, when issued  in basesrc, when you don't have corresponding
directory tree failes due to subdirectory is not created.
Is that made on purpose or are there other targets which should
be used to create that tree?

vishnu_219_> make includes
includes ===> include
install -r   -c  -o root -g wheel -m 444 arpa/ftp.h /usr/src/alpha-dist/usr/include/arpa/ftp.h
install: /usr/src/alpha-dist/usr/include/arpa: No such file or directory
*** Error code 1

Stop.
*** Error code 1

Stop.

My concern that it's annoying to do 'make includes; mkdir -p blabla' over
and over again. Is there any reason why it's not done the same way as
for syssrc(which creates target subdirectories)?
