Hey!
Anyone building ports against the current AROS master? Since 419fce0ab5 %build_with_cmake no longer takes installoptions, but ports' emulation/vbam/mmakefile.src still passes installoptions=. For me genmf.py then stops with Syntax error in arguments: installoptions= and mmake aborts ("Error regenerating makefile") whatever the target, as soon as ports/ is in the tree.
I have a one-line fix that just drops the empty argument (the old default was empty too, so older trees behave the same). Unless someone thinks I'm way off, I'll open a PR.
