Draft: store build artefacts in build folder.

Currently breaks with

portentax8-stm32h7-fw$ make
  CC        build/src/system_stm32h7xx_dualcore_boot_cm4_cm7.o
src/system_stm32h7xx_dualcore_boot_cm4_cm7.c:1: fatal error: cannot open build/src/system_stm32h7xx_dualcore_boot_cm4_cm7.su for writing: No such file or directory

compilation terminated.

Hi @facchinm ☕ 👋

Thank you very much for the fix 🙇 .

I would also like to remove the build folder, see c872df7 . Unfortunately, I'm not very happy with this solution (and for obvious reasons). If I replace it with

rm -rf $(BUILDDIR)

it would be more generic but empty the complete repositories content, as . is the default build directory.

Any suggestions to circumvent this?

Actually it does work, it's just not very clean ...

make clean
...
rm -rf .
rm: refusing to remove '.' or '..' directory: skipping '.'
make: *** [Makefile:207: clean] Error 1

You need to clean with BUILDDIR=build make clean 😉
