Subject: [PATCH] Makefile: Drop recursive invocation

We were running into issues when two targets are specified in
combination with multi-core builds (`-jX`), which led to race conditions
sometimes attempting to build the same file more than once at the same
time.

As we are only supporting POSIX builds now, the PLATFORM condition is not
necessary anymore. When introducing another platform in the future, we
should just pass the platform as variable to `make` to prevent us from
needing to invoke `make` recursively.
