build: resolve aconfigure location

[gjasny]

Come package managers like Conan prefer to use configure over aconfigure. Doing so right now fails if the working directory is not in the root of the source tree.

I am not familiar with Conan, just curious, why not change the working directory first before invoking configure as instructed by the docs: cd pjproject then ./configure? The aconfigure script itself also seems to require to be executed from the root of the source tree (e.g: ac_pjdir is set using pwd here).
