Yup. I agree this.

But this is irrelevant. I agree that sets of "single specified"
target is good. But I believe that the definition of sh-unknown-linux-gnu
(sh-linux in short) is supporting multiple targets.
It seems that you don't read my patch (and argument) sent to
gcc-patches at all. Could you please read it. Is the patch is OK for
Well, I explain again. My point is,
(1) We should support following four targets in GCC which is NOT multilibbed.
With those single specified architecture targets, you can build GCC,
with GNU C library. To do this, I need a patch I've sent to gcc-patches.
Do you agree this?
(2) Removing multilib from sh-unknown-linux-gnu is questionable for me.
I'm afraid of it just means let the target sh-unknown-linux-gnu
(3) If you don't like multilibbed environment, just not use
sh-unknown-linux-gnu, which supports multiple targets.
Instead, use single one.
(4) I believe that the target sh-unknown-linux-gnu means supporting
To suppurts those four targets, it uses multilib.
(5) Currently, GNU C library doesn't support multilibed installation.
However, you can manually set up the environment. Compile &
install & move for those four targets (four times).
