Here's how I'd configure and build GDB:

  mkdir binutils-gdb
  cd binutils-gdb
  git clone git://sourceware.org/git/binutils-gdb.git src
  mkdir build
  cd build
  ../src/configure .... all configure options here ....
  make all-gdb
  make check-gdb	# Optional, if you want to check it's working.
  make install-gdb

Configure options passed to src/configure will be forwarded to
src/gdb/configure automatically.

Hope that helps,

Thanks,
Andrew
