Update to 3.10.1.
For some months now, the build process of graphics/qgis 3.8.2 had problems
while using the QT5 QMap() function with large list like for proj6[1].
Compiling such long QMap() list with clang takes several hours instead of
some seconds or minutes[2], often it breaks the build.
It turns out that building that QMap() code with clang takes exhaustive
memory[3], for which a nice patch already exists on OpenBSD[4]. While this
OpenBSD patch builds fine on amd64, it needs another patch on i386 (usage of
'-O1' instead the clang specific patch '-mllvm -inline-threshold=128').
After we found a solution for the QMap problem, it was necessary to wait for
the release of QGIS 3.10.1 because of some tricky problems with proj6 / gdal
combinations[5] that should be avoided.
