It is tedious to specify extra compiler options for every file. HOST_EXTRACFLAGS is useful to add options to all files in a directory. -I$(src)/libfdt is needed for all the files in this directory to include libfdt_env.h etc. from scripts/dtc/libfdt/. On the other hand, -I$(src) is used to include check-in headers from generated C files. Thus, I added it only to dtc-lexer.lex.o and dtc-parser.tab.o .
