I was able to get a complete build with

  --disable-shared --disable-dl --enable-static
  F77=gfortran  FFLAGS="-O2 -pg"
  CXXFLAGS="-O2 -pg"
  CFLAGS="-O2 -pg"
  LDFLAGS="-pg"

I also needed to make these changes:

On startup, Octave complains about missing .oct files (not surprising,
they aren't built with the above configuration):

  warning: autoload: `besselj.oct' is not an absolute file name
  ...

I guess it's been a while since I (or maybe anyone else) has tried to
build a completely static version of Octave.  Maybe we should fix the
build process so that it works again.

Simply starting this copy of Octave and exiting generates an 8.6MB
gmon.out file on my system.
