[buildmasterotfs] too much verbosity

[frankrolf]

I am building a CFF2 variable font, using the typical buildmasterotfs/buildcff2vf workflow.
There are some glyphs I want to exclude from my build, which is why I am using the -gs option.

buildmasterotfs just uses makeotf, which emits these lines for each intermediate CFF2 OTF it generates:

My project has 12 source UFOs, which means I have roughly 12 * 50 = 600 lines of useless output.
Even in pure makeotf context, I’d be happy to just have a line 48 glyphs skipped (not in GlyphOrderAndAliasDB), to have the full output behind a --verbose flag.

All these lines make it difficult to parse the output.
