How did you find that out ? can you send your build configuration output
that bitbake prints when starting the build ?
secondly, TOOLCHAIN_OPTIONS is what decides this ABI
so when you use CC and CXX and friends, the right thing happens since it
will be appending TOOLCHAIN_OPTIONS to these vars. but if you use bare
cross compiler that will default to soft-float
