Building for MinGW on Windows

[seannowotny]

Hello, I would like to build the rive runtime for MinGW.
Running premake5 gmake2 in the build directory works fine.
A problem arrises when running mingw32-make from mysys2 mingw64. Log:

==== Building rive_harfbuzz (debug) ====
Creating windows/cache/obj/debug/debug/rive_harfbuzz
gsubgpos-context.cc

mingw32-make[1]: *** [rive.make:1003: windows/bin/debug/rive.lib] Error 1
mingw32-make: *** [Makefile:54: rive] Error 2

If anyone has faced this issue before and found a solution please let me know!
