Actually, there is a message in the output of ./configure:

R is now configured for i686-pc-linux-gnu

  Source directory:          .
  Installation directory:    /usr/local

  C compiler:                gcc -D__NO_MATH_INLINES -mieee-fp -g -O2
  C++ compiler:              g++ -mieee-fp -g -O2
  Fortran compiler:          g77 -mieee-fp -g -O2

  Interfaces supported:      X11, tcltk
  External libraries:        readline, BLAS(generic)
  Additional capabilities:   PNG, JPEG, bzip2, PCRE
  Options enabled:           R profiling

  Recommended packages:      yes


Note that in the above, the line "External libraries" indicates what
will be supported, which in my case, shows readline.

In addition, you can use capabilities() once in the R console to see
what has been included:

> capabilities()
    jpeg      png    tcltk      X11    GNOME     libz http/ftp  sockets
    TRUE     TRUE     TRUE     TRUE    FALSE     TRUE     TRUE     TRUE
  libxml     fifo   cledit  IEEE754    bzip2     PCRE
    TRUE     TRUE     TRUE     TRUE     TRUE     TRUE

In the above case, 'cledit' shows TRUE, which is the indication that
command line editing is supported.

On your final thought, you might want to review the following:
