[tlbuild] kpathsea r53235: web2cdir isn't created at install time any longer?

[balducci at units.it]

Hello

apologies if I'm reporting to the wrong list

While installing kpathsea r53235 (from svn) I get:

    ----8<----
     /bin/install -c -m 644 './texmf.cnf' '/opt/stow.d/versions/kpathsea-53235/usr/share/texmf.local/texmf-dist/web2c/texmf.cnf'
    /bin/install: cannot create regular file '/opt/stow.d/versions/kpathsea-53235/usr/share/texmf.local/texmf-dist/web2c/texmf.cnf': No such file or directory
    make[4]: *** [Makefile:2427: install-data-local] Error 1
    make[4]: Leaving directory '/home/balducci/tmp/install-us-d/kpathsea-53213.d/source/texk/kpathsea'
    ---->8----

I have noticed that since r53213 (the last version I installed)
Makefile.in has undergone some changes, in particular
$(DESTDIR)$(web2cdir) has gone from the installdirs-am target: just
wondering if that is a typo or I should change my installation script
in some way.

The following works around the build for me:

    ----8<----
    *** ./Makefile.in.INSTALL_DIR_WEB2CDIR Thu Dec 26 10:41:29 2019
    --- ./Makefile.in Thu Dec 26 10:41:29 2019

Configuring with:

thanks a lot for your valuable work
