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.
