add -r flag

Produce a relocatable object as output (partial linking). Necessary for latest emsdk.

I tried that, but I still get this error:

It only works for me with -s USE_FREETYPE=1 and PLATFORM_CORE_EXCLUSIONS += $(OF_LIBS_PATH)/freetype/lib/%

[themancalledjakob]

hmmm.. so that would actually ignore the precompiled library. could it be, that the freetype lib in $OF_ROOT/libs/freetype/lib/emscripten/ was compiled with a different emsdk than you used to compile fontsExample? That would explain the function signature mismatch, I think.

@themancalledjakob it was the same version. we actually had a fix for this, but since it is working with the prebuild lib it is not needed anymore (would still be nice to fix the oflib for that): https://github.com/openframeworks/openFrameworks/pull/6764
