[QGIS-Developer] Build failure in master

[Tom Elwertowski]

Try deleting everything in the {build}/python/analysis folder. Just 
deleting the generated *.cpp files isn't enough.

I have been seeing a multiple definition sip_{module}part{n} 
sip_{module}part{n+1} error about once every three months for awhile. 
Deleting everything in {build}/python/{module} allows the build to be 
resumed (macOS Catalina).
