In particular, I would like it if:

   "gnumake install" if I want to install it.
    

+1

  

2. I didn't have to edit various files in <EPICS base>/configure or set
   environment variables to tell the EPICS build system where things
   are and what my host hardware architecture is.  It's of course great
   to be able to change these, but I would love good defaults for the
   simple case where I just want it to compile out of the box for the
   current host without having to do a lot of work.
    

With the exception of setting EPICS_HOST_ARCH this already works for my 
favourite platform (kubuntu-linux). Cross-compiling is another matter, of 
course...

We just added the following lines in epics base configure/CONFIG_SITE to set EPICS_HOST_ARCH.
Not sure why this isn't the default.

# If EPICS_HOST_ARCH is not set, derive it
ifndef EPICS_HOST_ARCH
EPICS_HOST_ARCH=$(shell $(EPICS_BASE)/startup/EpicsHostArch.pl)
export EPICS_HOST_ARCH
endif
