Changes insisted by your code (and ONLY your code, btw):

  ./configure \
  --enable-eaccelerator=shared \
  --with-eaccelerator-shared-memory \ 
  --with-php-config=$PHP_PREFIX/bin/php-config

Again, this should be done properly, so that individuals DON'T have to recompile and reconfigure eacc, especially when they can't.

Where exactly are these configuration options set or changed?

I'm having the same issue: eAccelerator is installed and working (as far as I know). phpinfo shows:
