If the build directory is mounted via nfs, then sudo make install will fail with the following error:

make  install-data-hook
  GEN      libglib-gdb.py
/bin/sh: ./libglib-gdb.py: Permission denied
make[5]: *** [libglib-gdb.py] Error 1
make[4]: *** [install-data-am] Error 2
make[3]: *** [install-am] Error 2
make[2]: *** [install-recursive] Error 1
make[1]: *** [install] Error 2
make: *** [install-recursive] Error 1

The problem is that install-data-hook tries to create the file libglib-gdb.py in the build directory at install-time, but this is not allowed when the uid is root.

A similar problem occurs with libgobject-gdb.py.

The attached patch fixes this by adding a makefile dependency to create the files at build-time.  The patch is against the release tar, hence it contains changes to Makefile.in rather than Makefile.am.
