No, sorry.  In gcc, binutils, gdb, newlib, et al; there is a toplevel
configure and Makefile.  Configure programatically determines which of
the available source directories will participate in the build, and
creates a suitable Makefile.  The Makefile calls the sub-configures in
turn.  They share config.cache, because it saves a lot of time.

So, yes, configure is getting called a lot, from different modules, at
different times.
