I should have been a little more specific:

The recommended way to build gcc is to use a clean directory outside
the source tree somthing like this:

  mkdir build_dir
  cd build_dir
/path/to/gcc_src/configure <options>

I want to know if there is a preferred or defined way to refer to
"/path/to/gcc_src" in build scripts or configure inputs since
"$(srcdir)" seems to be locally defined per Makefile.

Thanks.
