Fix the following build break by adding a conditional definition
of EM_RISCV in order to allow cross-compilation on machines
which do not have EM_RISCV definition in their host.
build break log from [1]:
scripts/sorttable.c:352:7: error: use of undeclared identifier 'EM_RISCV'

This is happening for us when we try to build ARM(64) cross-builds on Ubuntu 16.04. Yes, I know, that's a fairly old distro. At the same time it isn't ancient (extended support is still available), and it *should* be possible to build the 5.15 kernel on it. And yes, some of our build machines have been updated to Ubuntu 20.04, but not all of them. We'll get there eventually. For now this error is posing a bit of a problem. > > Michal > > > > > > [1] > > > > https://urldefense.com/v3/__https://lore.kernel.org/lkml/e8965b25-f15b-c7b4-748c-d207dda9c8e8@i2se.com/__;!!CTRNKA9wMg0ARbw!2wBeUUDf3Z2m7uJLF51GeZnBFWXRlEQrzGJ72JWIT0MPUcS_RgW98QWTXkEjy9-lhg$ > > > > > > > > > > > > Cc: Jisheng Zhang <jszhang@kernel.org> > > > > Reported-by: Stefan Wahren <stefan.wahren@i2se.com> > > > > Fixes: 54fed35fd393 ("riscv: Enable BUILDTIME_TABLE_SORT") > > > > Signed-off-by: Miles Chen <miles.chen@mediatek.com> > > > > > > Reviewed-by: Jisheng Zhang <jszhang@kernel.org> > > > Hi Andrew, > > I cannot find the maintainer for scripts/sorttable.c, would you pick > up this change, please? Yes, please. I've been looking at failed nightly builds since September 12. It's only a forward looking build (so nothing mission critical), but it would still be nice to have it build again.
