While python3 module use cython to build library, the generated source file is not stable at each build and made the generated library not be reproducible This commit replaces un-predictable string with hardcode string in generated source file to assure the generated library should be reproducible (From OE-Core rev: 61d98d12eca1c7bdf3b7387a820c83d3b8fad965) Signed-off-by: Hongxu Jia <hongxu.jia@windriver.com> Signed-off-by: Mathieu Dubois-Briand <mathieu.dubois-briand@bootlin.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>

Subject: [PATCH] Replace not predictable build path prefix with hardcode
|

string in the generated output file
|
|
|
|
The build path may contain tmp dir which is not predictable, it caused
|
|
the generated output file is not stable at each build and made
|
|
the generated library is not reproducible [1] between builds
