toolchain/toolchain-external: don't use x$(...) construct or ==

With modern shells, we can simply do test using the "$(...)" = "value"
form. This commit gets rid of the x$(...) = x"value" constructs and
replaces == by =, which is the correct operator to test the equality
of two strings with the test program.
