+Use a python variable instead of hardcoding Python
+
+The nodejs build system uses python in a number of locations. However,
+there are some locations where it hardcodes 'python' as the Python
+interpreter. However, this causes problems when we need to use python2
+instead of just python.
+
+This patch fixes that by using the python variable already in place in
+the nodejs build system.

When Python 3 is selected in Buildroot, the host/usr/bin/python symlink of the host Python interpreter points to python3. Packages that need to use the host Python 2 interpreter have to use python2. In commit 40218a16526946f35dab0d05f379f71a01f29530 ("nodejs: force python interpreter"), Samuel made some changes to the nodejs package to use python2. One part of the changes is to sed a .gyp file to replace the string 'python' by the path to python2. However, this operation is done *after* calling the configure script, so it has in fact no effect. Putting this sed before calling the configure script fixes the problem. However, there is a better solution: the nodejs build system has a mechanism of variables, and it already defines a python variable according to the environment variable PYTHON being passed. So this patch instead adds a new patch to nodejs to use this python variable.
