You need to run configure from the top level.
../binutils-gdb/configure ...
../binutils-gdb/gdb/configure ...

gdb uses several libraries in the binutils-gdb repo and those must be
built first.

You're probably worried that if you run the top level configure and
then do "make" that will build everything including
gas,ld,binutils,etc. and not just the gdb you want.
One solution to this is to do "make all-gdb" instead of "make".

There are also configure options to disable building of pieces so that
"make" will then build just gdb.
../binutils-gdb/configure --disable-gas --disable-binutils
--disable-ld --disable-gold --disable-gprof

[I think(!) I spelled those right and I think(!) I remembered
everything to disable.]
