I just checked the old CVS build toplevel Makefile which contains such script:
SUBDIRS =  intl libiberty opcodes bfd readline libdecnumber sim gdb etc

Now, the new Git build toplevel Makefile has more sub dirs:
SUBDIRS =  intl libiberty opcodes bfd readline libdecnumber binutils gas ld sim gdb gprof etc
