"i386--netbsdelf-gcc: .: linker input file unused because linking not

You have to test with "HAVE_GCC=3 or HAVE GCC=4"

I've got this error message a few days ago ...

I'm able to build a complete release with HAVE_GCC=3

Try this ... I know it's fastidious but this may solve your problem.

What is the release you are using to build the current-release ?
