[issue31713] python3 python-config script generates invalid includes

[matthewlweber]

New submission from matthewlweber :

Related to https://bugs.python.org/issue22907

If building in a path that starts with /usr, the includedir=$(echo 
"@includedir@" | sed "s#^$prefix_build#$prefix_real#") assignment in the 
python-config.sh ends up having the path it processes ran through a path 
substitution once before this line is executed because the @includedir@ in the 
python-config.sh.in is set to the string '${prefix}/include'.  ${prefix} is 
assigned just above includedir in python-config.sh to prefix=$(echo 
"$prefix_build" | sed "s#^$prefix_build#$prefix_real#")

I believe we need to update the includedir to 

includedir=$(echo "@includedir@")

Or rename the prefix variable in python-config.sh so that there isn't a naming 
conflict if a string is passed in via @includedir@ with that variable.

Without fixing this you end up with multiple /usr substitutions in the 
includedir string, each replaced with the real path.  ie resulting in an 
invalid path.
