ostinato: make build more standard
This is just a proposal, it won't fix any bugs.
I don't like the current complex make command in build(), I would like a more standard one. To achieve that, I patched the QMAKE_CXXFLAGS in
options.pri instead of using CXXFLAGS in the make command.
Futhermore I prefer the Debian modeltest patch https://salsa.debian.org/debian/ostinato/blob/master/debian/patches/extra-modeltest-workaround.diff, so I integrated that patch.
Here my patch: ostinato_alpine.diff
I tested that only with alpine v3.12.1 on x86_64.
