rustc: Fix cross-compilation for the targets with dot in name
When you are trying to cross-compile rustc to the target platform with
the dot in name, e.g. "thumb8vm.main-none-eabi", rustc compilation fails
with this error during configuration:

This is probably related to
https://github.com/rust-lang/rust/issues/130602 and thus target string
should be double-quotted so bootstrap/configure.py can parse it
correctly.
Changes tested on x86_64-linux build machine with rustc built for
"thumb8vm.main-none-eabi" target.
