Re: ./build.sh -O ../obj tools producing error

And now, I'm really screwed.......   I grabbed the latest "base.txz" for
aarch64 and successfully located the ./lib/ directory and sure enough, that
libc.so did have  __sigaction_siginfo

Great!

so cp -rp that lib directory to /lib2

then:

# cd /
# mv lib lib0      ;;; rename old lib as lib0
# mv lib2 lib      ;;;; rename new libs as /lib
mv: Shared object "libc.so.12" not found

And, in fact, pretty much every command except "pwd" so far needs a shared
library it can't find.

Sigh, is there a way to fix this?  Or am I totally hosed?
Naturally, remote access does not work, either.

# shutdown -h now
shutdown: Shared object "libc.so.12" not found

I long for the days when we thought we had enough memory so we could afford
to have static binaries lying around.... ;-)
