readline-8.0-alpha: Makefile.in: don't forget to create pkgconfigdir

[gabriele balducci]

hi

just tried to build/install readline-8.0-alpha and found the following
glitch:

----8<----
/bin/install: cannot create regular file 
'/opt/stow.d/versions/readline-8.0-alpha/usr/lib64/pkgconfig/readline.pc': No 
such file or directory
make[1]: *** [Makefile:245: install-pc] Error 1
make[1]: Leaving directory 
'/home/balducci/tmp/install-us-d/readline-7.0.d/readline-8.0-alpha'
---->8----

The reason seems to be the installdirs target in Makefile.in missing to
create $(DESTDIR)$(pkgconfigdir).

This fixes things for me:


diff -c ./Makefile.in.CREATE_PKGCONFIGDIR ./Makefile.in
*** ./Makefile.in.CREATE_PKGCONFIGDIR   Thu May 24 17:23:06 2018
--- ./Makefile.in       Thu May 24 17:23:06 2018
