This wrapper is useful independently of pandoc-drawio-filter — it's
useful in any other situation in which somebody might want to use
draw.io diagrams in a build process.
So, make it accessible from the top level to facilitate reuse.
Workaround build failure on -fno-common toolchains like upstream
gcc-10. Otherwise build fails as:
ld: ../obj/unix/tiles.o:/build/grafx2/src/global.h:306: multiple definition of
`Main_selector'; ../obj/unix/main.o:/build/grafx2/src/global.h:306: first defined here
3.1.9 had issues with building and 3.1.10 has been released fixing
those; a parallel building error has been found and it is fixed on
Gentoo repository, from where we grab the patch from.
