--- Comment #4 from Andrew Pinski <pinskia at gcc dot gnu.org> ---
Part of the problem is *-uclinux is not matched in config.gcc where
linux-protos.h/linux.o gets added:
```
*-*-linux* | frv-*-*linux* | *-*-kfreebsd*-gnu | *-*-gnu* |
*-*-kopensolaris*-gnu | *-*-uclinuxfdpiceabi)
...
  # Linux C libraries selection switch: glibc / uclibc / bionic.
  # uclibc and bionic aren't usable for GNU/Hurd and neither for GNU/k*BSD.
  case $target in
    *linux*)
      tm_p_file=3D"${tm_p_file} linux-protos.h"
      tmake_file=3D"${tmake_file} t-linux"
      extra_objs=3D"${extra_objs} linux.o"
      extra_options=3D"${extra_options} linux.opt"
      ;;
  esac

```

As I mentioned there seems to be some misunderstanding what is the canonical
form for the triplet, or is both canonical (and different?) and just need f=
ix
the usage for when uclinux is used and have them set tm_p_file/extra_objs
correctly, if they use linux.h .=
