Yes, the details of how the autotools are built can be found in inside
of autoconf-rtems.spec and automake-rtems.spec

It basically is the standard procedure to install the packages, ie.

cd <somewhere>
tar xzvf autoconf-2.52.tar.gz
cd autoconf-2.52
./configure --prefix=/opt/rtems
make install

cd <somewhere>
tar xzvf automake-1.6.3.tar.gz
cd automake-1.6.3
./configure --prefix=/opt/rtems
make install

The rpm.specs add some "nice-to-have" convenience stuff to these
packages (man-page generation etc.), but this is not necessary for
proper operation. The sequence above should be sufficient.

I don't fully understand your question, but you seem to be asking what
the "cd scripts; ./configure ... etc." I described in my previous mail

It generates the rpm.specs for all RTEMS's  rpms, including the
autotools, binutils, gcc/newlib, gdb, and further packages.
