Ah, I thought that we already needed two different versions for GDB, 
because of this line in gdb/configure.ac:

  AC_PREREQ(2.59)

But the real requirement is 2.64, and seems to come from 
config/override.m4 (not sure how it's invoked though).  This applies to 
all projects under binutils-gdb, but also in the gcc source repository, 
doesn't it?  So we would need to change all of binutils-gdb and gcc at 
the same time, in sync?
