make buildworld fails

[Sperber]

Hi there

make buildworld fails as a directory in obj is not created:
/usr/obj/usr/src/i386/legacy/usr/include/c++/3.3
(it fails at the beginning of make world)

sh /usr/Data/usr/src/tools/install.sh -C -o root -g wheel -m 444  /usr/Data/
usr/src/usr.bin/lex/FlexLexer.h /usr/obj/usr/Data/usr/src/i386/legacy/usr/
include/c++/3.3                                                                                                                                                       
install: /usr/obj/usr/Data/usr/src/i386/legacy/usr/include/c++/3.3: No such 
file or directory

(a mkdir while make buildworld is running overrides the error)
