'distcheck' target broken in '7.7' branch

[carlosabalde]

Basically, this is the problem:

$ make distcheck
...
rm -f config.h stamp-h1
rm -f libtool config.lt
rm -f TAGS ID GTAGS GRTAGS GSYMS GPATH tags
rm -f cscope.out cscope.in.out cscope.po.out cscope.files
make[2]: Leaving directory '/home/dev/varnish-modules/varnish-modules-0.26.0/_build/sub'
rm -f config.status config.cache config.log configure.lineno config.status.lineno
rm -f Makefile
ERROR: files left in build directory after distclean:
./src/vmod_vcs_version.txt
make[1]: *** [Makefile:832: distcleancheck] Error 1
make[1]: Leaving directory '/home/dev/varnish-modules/varnish-modules-0.26.0/_build/sub'
make: *** [Makefile:761: distcheck] Error 1

I encountered the same issue in my own VMODs, and this is how I resolved it. However, I'm not entirely sure if this approach is correct, as it doesn't fully align with the upgrade notes for VMOD developers. I pass this to the autotools experts :)

You didn't read the release notes? 😁

I read these! Point taken though, thanks Pop!
