There ain't anything broken with these packages ;)
They do not leave files around, nor do they do anything harmful. They
simply do not fit into the constraints you are trying to set up.

Why? rpmbuild and the spec have full access to both directories and can
read/write to both.
Whether a package does a
%build
make something
make install-something DESTDIR=$RPM_BUILD_ROOT
export LD_LIBRARY_PATH=$RPM_BUILD_ROOT%{_lib}
make all
%install
rm -rf $RPM_BUILD_ROOT
make install DESTDIR=$RPM_BUILD_ROOT
or a
%build
make something
make install-something DESTDIR=$(PWD)/tmp
export LD_LIBRARY_PATH=(PWD)/tmp%{_lib}
make all
%install
rm -rf $(PWD)/tmp
rm -rf $RPM_BUILD_ROOT
make install DESTDIR=$RPM_BUILD_ROOT
doesn't make a real difference.
To the contrary, the later is sightly more error-prone.

<sigh/> IMO, you are trying to overengineer something.
