install.sh verify-install step does not honor ${CFG_DESTDIR}

[gbsf]

At install-template.sh:724-725, the script tries to run the binaries without taking in consideration the destination dir.
Thus, running make DESTDIR=… install will always fail. I also couldn't find a --disable-verify-install switch to make install, as the error message says.

As an aside, the comment above that block also needs changing.

Thanks for the report! I'm spending some time on rust-installer this week and will try to get this fixed soon.

Fix is on my 'next' branch. Will take a week or two to find its way into rust.

install.sh --help shows the --disable-verify option for me.

I was running make install on the rust repo, so I had no way to manually invoke install.sh.
In any case, I found the --disable-verify-install switch. But it is in ./configure, not in make install like the error message says.
