README needs to be updated for prerequisites

[ThinkOpenly]

It would be helpful to organize and update the prerequisites section ("1.2 Packages") of README.txt. Some packages are no longer prerequisites in later AT releases due to the removal of included packages like OProfile.

Also, I'm not sure everything is listed that needs to be. On a recent build on a RHEL8 system, I thought I had installed all prerequisites, and got the following errors in sanity.log:

Couldn't find autoconf-archive required to proceed the build.
Couldn't find autogen-libopts required to proceed the build.
Couldn't find docbook-style-xsl required to proceed the build.
Couldn't find docbook2X required to proceed the build.
Couldn't find libffi-devel required to proceed the build.
Couldn't find libstdc\+\+-static required to proceed the build.
Couldn't find qt5-devel required to proceed the build.
Couldn't find rpm-build-[0-9] required to proceed the build.
Couldn't find rpm-sign required to proceed the build.
Couldn't find sqlite-devel required to proceed the build.

...maybe it could list actual package names by supported distro, and maybe it could even provide a script or a Makefile target to ensure the packages are installed, rather than just checking and then failing.
