Drop shell for loops in favor of makefile pattern rules,
so make can run targets in parallel using -j.
This doesn't affect Vivado's own settings.
As a benchmark, 12th Gen Intel(R) Core(TM) i9-12900H 5GHz(max):
$ make -C projects/adrv9009/zcu102/ clean-all
$ time make -C projects/adrv9009/zcu102/ -j$CORES lib
CORES=1:
real 9m27.223s
user 9m2.556s
sys 0m32.358s
CORES=8:
real 1m54.639s
user 16m26.512s
sys 1m2.317s
i.e. about 5 times faster to build IP core dependencies.
