[Buildroot] [git commit] xapp_xload: fix musl build

[Thomas Petazzoni]

commit: https://git.buildroot.net/buildroot/commit/?id=fe0607e68beeec7d33693194b76f7fff8e9be2ef
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

xapp_xload tries to include protocols/rwhod.h, which isn't available on
musl. Fortunately, the package also has stub code that can be enabled
with -DRLOADSTUB (this is done e.g. on Cygwin).

This should probably be detected in configure, but that's a lot more
work.
