Subject: [PATCH] python-config.sh: don't reassign ${prefix}

When prefix is set to a path like /usr during crossbuild
the sed operations end up executing twice, once for the prefix
reassignment and another for includedir if it is set as a string
including the ${prefix} variable.  This results in an issue
when the build directory is under /usr.

This patch updates the remaining location which uses the prefix
variable to also sed and update to use the real path.

Upstream bug report:

Buildroot bug:

Fixes failures like the following:
