I just checked it out with my toolchain collegues, they said the
option is -mbaseline.
Please use 'nds32le-linux-gcc --target-help' to check what machine
related options could be used.
But, they remineded me, if you don't use the default baseline setting
of the toolchain, the behavior might
lead crash or some unknown problem.
I'll check it later.

However, you cannot generate v0 baseline with any other toolchains,
only v0 toolchain can do.
Sorry. :-(
