I don't know about the other parts of src, but GDB always supported
in-tree builds, even though we advise in README to do it outside the
source tree:

    You can build GDB right in the source directory:

	  cd gdb-6.3
	  ./configure
	  make
	  cp gdb/gdb /usr/local/bin/gdb     (or wherever you want)

    However, we recommend that an empty directory be used instead.
    This way you do not clutter your source tree with binary files
    and will be able to create different builds with different
    configuration options.
