I am able to do 'devtool modify gpgme' without any errors. In what setting
does it fail for you?
The purpose of _sysconfigdata is to substitute configuration values that
are specific for target python when running native python in cross builds
with requests from target component build systems to supply those values.
For that to work, the recipe also needs to have target python3 in its
DEPENDS. It
I feel the patch is fixing the symptom rather than the issue somehow?
