make sharedinstall does not create lib-dynload in DESTDIR if lib-dynload exists in system already #100221
Description
Bug report
The Makefile.pre.in rule for creating directories is specified as:
$(DESTSHARED): @for i in $(DESTDIRS); \ do \ if test ! -d $(DESTDIR)$$i; then \ echo "Creating directory $$i"; \ $(INSTALL) -d -m $(DIRMODE) $(DESTDIR)$$i; \ else true; \ fi; \ done This means that if $(DESTSHARED) exists already (note: missing $(DESTDIR)!), i.e. Python 3.12 has been installed into the system, the directories in $(DESTDIR) won't be created and the successive sharedinstall rules fail due to the missing destination, e.g.:
/usr/bin/install -c -m 755 Modules/array.cpython-312-x86_64-linux-gnu.so /usr/lib/python3.12/lib-dynload/array.cpython-312-x86_64-linux-gnu.so /usr/bin/install: cannot create regular file '/var/tmp/portage/dev-lang/python-3.12.0_alpha3/image/usr/lib/python3.12/lib-dynload/array.cpython-312-x86_64-linux-gnu.so': No such file or directory /usr/bin/install -c -m 755 Modules/_asyncio.cpython-312-x86_64-linux-gnu.so /usr/lib/python3.12/lib-dynload/_asyncio.cpython-312-x86_64-linux-gnu.so /usr/bin/install: cannot create regular file '/var/tmp/portage/dev-lang/python-3.12.0_alpha3/image/usr/lib/python3.12/lib-dynload/_asyncio.cpython-312-x86_64-linux-gnu.so': No such file or directory /usr/bin/install -c -m 755 Modules/_bisect.cpython-312-x86_64-linux-gnu.so /usr/lib/python3.12/lib-dynload/_bisect.cpython-312-x86_64-linux-gnu.so /usr/bin/install: cannot create regular file '/var/tmp/portage/dev-lang/python-3.12.0_alpha3/image/usr/lib/python3.12/lib-dynload/_bisect.cpython-312-x86_64-linux-gnu.so': No such file or directory Full log: dev-lang:python-3.12.0_alpha3:20221207-142002.log
