No. That's the user visible item to set. It should be assigned to a variable in confdefs.h. You want the variable.  This CONFIGURE_xxx value is only visible with the user value in the file where the user instances the configuration. This is the line.

    int imfs_rq_memfile_bytes_per_block = CONFIGURE_IMFS_MEMFILE_BYTES_PER_BLOCK;

So you want that variable.

FWIW  I actually managed to ssh to oar, grep, and copy that from my phone. :)
