Re: netbsd-9 cross-buidl tools fail

[Lloyd Parkes <lloyd%must-have-coffee.gen.nz@localhost>]

I've seen this before. We are using an old version of the dtc source 
code that no longer builds with modern C compilers. GCC finally became a 
bit more compliant in that way somewhat recently uncovering this broken 
code.

The proper fix will be to import a newer version of dtc into the 
netbsd-9 branch.

A quick fix might be to simply delete the line defining yylloc in 
external/gpl2/dtc/dist/dtc-lexer.l (line 43 in my copy).

Cheers
