Thanks for the report.

I can confirm this is reproducible.

Creating the directories manually is sufficient to work-around this, e.g.:

    tar -xf sed-4.3.tar.xz
    mkdir build ; cd build
    ../sed-4.3/configure --disable-dependency-tracking
    mkdir lib sed
    make

In sed's "doc/local.mk" there is an explicit command to create the 'doc'
directory:

    doc/sed.1: sed/sed$(EXEEXT) .version $(srcdir)/doc/sed.x
            $(AM_V_GEN)$(MKDIR_P) doc
            [...]

So we can easily add similar commands for 'sed' and 'lib' directories
(I'm just looking for the optimal place to add this).
