nbdtab_lexer.l includes nbdtab_parser.tab.h, which in turn is dynamically generated during the build from nbdtab_parser.y. Specifying nbdtab_parser.tab.h in BUILT_SOURCES avoids a potential race condition where parallel make can fail if nbdtab_lexer.l is processed before nbdtab_parser.tab.h has been created.
