Subject: [PATCH] Fix the commands to build library

In `scripts/common.make`, used by `tests/Makefile` and `programs/Makefile`,
we have the following rules to build the library:

  ```
  $(MBEDLIBS):
      $(MAKE) -C ../library
  ```

$(MBEDLIBS) contains three library files but the command is for all
the 3 files instead of single target generation. This would cause a
race when doing parallel build. This commit fixes command so that
the recipe could generate a single library file.

Fix https://github.com/Mbed-TLS/mbedtls/issues/8229
