Add COMPILEALL_OPTS variable in Makefile to override compileall options (default: -j0) in "make install". Merge also the 3 compileall commands into a single command building PYC files for the 3 optimization levels (0, 1, 2).

Example:

./configure --prefix ~/prefix
make
make install COMPILEALL_OPTS="--hardlink-dupes -j4"

Output:

(...)
PYTHONPATH=/home/vstinner/prefix/lib/python3.12  \
	./python -E -Wi /home/vstinner/prefix/lib/python3.12/compileall.py \
	-o 0 -o 1 -o 2 --hardlink-dupes -j4 -d /home/vstinner/prefix/lib/python3.12/site-packages -f \
	-x badsyntax /home/vstinner/prefix/lib/python3.12/site-packages
(...)

compileall is called with options: -o 0 -o 1 -o 2 --hardlink-dupes -j4:

  • -o 0 -o 1 -o 2 is hardcoded
  • default -j0 was overriden with --hardlink-dupes -j4

I tested again to double check. Ah, in fact compileall is called two times: once for Lib/, once for site-packages:

(...)

PYTHONPATH=/home/vstinner/prefix/lib/python3.12  \
        ./python -E -Wi /home/vstinner/prefix/lib/python3.12/compileall.py \
        -o 0 -o 1 -o 2 --hardlink-dupes -j4 -d /home/vstinner/prefix/lib/python3.12 -f \
        -x 'bad_coding|badsyntax|site-packages|test/test_lib2to3/data' \
        /home/vstinner/prefix/lib/python3.12
Listing '/home/vstinner/prefix/lib/python3.12'...
(...)

PYTHONPATH=/home/vstinner/prefix/lib/python3.12  \
        ./python -E -Wi /home/vstinner/prefix/lib/python3.12/compileall.py \
        -o 0 -o 1 -o 2 --hardlink-dupes -j4 -d /home/vstinner/prefix/lib/python3.12/site-packages -f \
        -x badsyntax /home/vstinner/prefix/lib/python3.12/site-packages

This is an improvement, thanks! OTOH we would probably also like an opinion to disable this entirely and do it ourselves.

That can be a separated option.

IMO this change alone is already an enhancement ;-)
