Fix handling of BUILD_SUFFIX in remote-gdb script

When CONFIG_BUILD_SUFFIX is enabled, the target-* folders in build_dir
and staging_dir have this suffix in the name, but not the
toolchain directories. When detecting the names for "arch" and "libc",
also accept the suffix and do not use it for the toolchain path.
