some targets fail to build

[Király Tamás]

Hi,

I downloaded binutils 2.39 and inspected bfd/config.bfd to generate a list of targets which should cover every cases. i then processed and reformatted the text to make it digestable to the ./configure --target <triplet>.

i found that using various triplets, building binutils fails. It mostly fails at configure part but some of them fail during compilation. There are various error messages like:

  *   ld does not support target
  *   This target is no longer supported in gas


here is a list of failing targets:

Maybe they are indeed bad triplets, i don't know, but probably bfd/config.bfd is less strict than it should. Anyone any thoughts?
