Is this yet another quiet autoconf change? Formerly,
program_transform_name didn't do anything in the case where host_alias
and target_alias were the same.
I see that now it does something whenever target_alias is set. I
can't see any documentation about this behaviour, but then the old
behaviour probably wasn't documented either.
I guess my question is: why is --target being passed down from the top
level in the native case? I thought part of the autoconf conversion
was that the top level had to stop passing down --target all the time.
Anyhow, I think it would be moderately useful if `make install' worked
correctly in the gas subdirectory. I don't know what is required to
make that happen.
