After doing
./autogen.sh && ./configure && make
make clean
make distclean
and moving .gitignore aside, the following files still remain after this patch:
Makefile.in
aclocal.m4
autom4te.cache/
build-aux/compile
build-aux/config.guess
build-aux/config.sub
build-aux/depcomp
build-aux/install-sh
build-aux/ltmain.sh
build-aux/m4/libtool.m4
build-aux/m4/ltoptions.m4
build-aux/m4/ltsugar.m4
build-aux/m4/ltversion.m4
build-aux/m4/lt~obsolete.m4
build-aux/missing
build-aux/test-driver
configure
doc/man/Makefile.in
src/Makefile.in
src/config/bitcoin-config.h.in
Most are automake related so I guess it's fine if they litter around.
