[PATCH liburing v3 0/4] Changes for Makefile

[Alviro Iskandar Setiawan <alviro.iskandar@gnuweeb.org>]

Hello sir,

This patchset (v3) changes Makefile. 4 patches here:

1. Remove -fomit-frame-pointer flag, because it's already covered
   by the -O2 optimization flag.

2. When the header files are modified, the compiled objects are
   not going to be recompiled because the header files are not
   marked as a dependency for the objects.

  - Instruct the compiler to generate dependency files.

  - Include those files from src/Makefile. Ensure if any changes are
    made, files that depend on the changes are recompiled.

3. The test binaries statically link liburing using liburing.a file.
   When liburing.a is recompiled, make sure the tests are also
   recompiled to ensure changes are applied to the test binary. It
   makes "make clean" command optional when making changes.

4. Same as no. 3, but for examples.

please review,
thx
