[Bug bootstrap/30678] sysmacros.h get currupt from Fixincludes with updated glibc.

I'm looking at the inclhack fix now:

> fix = {
>    hackname  = glibc_c99_inline_4;
>    files     = sys/sysmacros.h, '*/sys/sysmacros.h';
>    bypass    = "__STDC_VERSION__";
>    c_fix     = format;
>    c_fix_arg = "\n#if __STDC_VERSION__ < 19901L\nextern\n#endif\n";
>    c_fix_arg = "extern";
>    test_text = <<-EOT
>	__extension__ extern __inline unsigned int
>	EOT;
> };

Unfortunately, there is no commentary about intended purpose and the current
discussion does not explain exactly what is needed.  I am going to take a guess
that the __extern_inline macro will not ever need this special treatment.
Therefore, the fix should look like the following.  Comments, please?

> fix = {
>     hackname  = glibc_c99_inline_4;
>     files     = sys/sysmacros.h, '*/sys/sysmacros.h';
>     bypass    = "__STDC_VERSION__";
>     select    = ' extern ';
>     c_fix     = format;
>     c_fix_arg = "\n#if __STDC_VERSION__ < 19901L\nextern\n#endif\n";
>     test_text = <<-EOT
> 	__extension__ extern __inline unsigned int
> 	EOT;
> };
