Yes, because binutils uses the cygnus build system. It is not DJGPP specific.
In this system almost every directory has its own configure script that must be run to create the required makefile.  In the Autoconf/Automake build system usually there is only a configure script in the top source directory that configures and creates  all makefiles in the source tree.
The DJGPP specific build.sh makes DJGPP specific changes to all configure scripts, then it runs the configure script in the top source directory creating the makefile.  If this is successful, build.sh starts makefile and this makefile goes recursively through the source tree running first the configure script to create the makefile for that directory and then running the produced makefile.
This is all cygnus specific and is not related to the DJGPP port.  The top source directory configure scripts creates the top source directory makefile, then this makefile is executed and goes recursively through the tree executing first the configure script that creates the makefile and then executing the makefile.
