I am the (proud?) owner of a Lemote Fuloong 2F¹² that has been sitting
in a desk drawer for a few years now which I want to get back up and
running. Before I put it away I had installed Debian 8 (I'm pretty sure)
and used snapshot.debian.org to get a usable apt repository. At some
point the baseline in Debian moved past what this machine can support,
and I'm having a hard time finding information about what flags to pass
to various programs to build software which will run on this device.

You need
-march=mips3
-mfix-loongson2f-nop

The recent Debian releases is using mips32r2/mips64r2, thus
they cannot work with Loongson 2F.

You might also look at Deepin. It is Debian based, the companies
involved in Loongson are also involved in Deepin.
