Comment (by takeshi@…):

 Thank you for pointing this. I didn't know ccache and have just found out
 what it is. h4cc is provided by the upstream so I'd rather leave it. While
 I understand I should respect {{{configure.compiler}}}, but h4cc script is
 used to make the same compiler consistently. A quick fix would be to set
 {{{configure.ccache no}}} as in #30258, but I'll see what I can do for
 improvement.
