build: Don't use non-POSIX tests

The `test` builtin/binary usually accepts `==` for string comparison, it is
mostly accepted for typos and people being used to double equals, but is not
documented and not always accepted either.  Since autoconf uses the default
shell, it might just fail in some cases with:

    ./configure: 29986: test: xrustc: unexpected operator
    ./configure: 29990: test: xcargo: unexpected operator

Just change it to single equals as it is done everywhere else.
