Thanks

Yup.  To me, anything other than /lib is non-standard for glibc :-)

I see.

Ah, I should have figured it out :-)

I do see your point.  I had just asked you to satisfy my curiosity :-)

As long as it mentions the --disable-target-dir-sanity-checking
option, it's fine with me.

Nope, it just doesn't make sense.  -d ${srcdir}/newlib might make some
sense, but even then, I don't think it's The Right Thing (TM) to test
for.  Let's just keep the current set of tests, plus the additional
configure option, and see how it works.

Bad idea, I admit :-)

Yes, please.  Hopefully, the last iteration :-)
