When building for armhf and running an arm64 kernel, the configure
script uses "uname -m" to determine the architecture for KYUA_PLATFORM,
but this introduces variations depending on the kernel used to perform
the build:

  632 ··0x000837d0·61617263·68363400·556e7375·70706f72·aarch64.Unsuppo


While this is often worked around in chroots by running with a "linux32"
personality, using the running kernel is not the correct way to
determine the architecture.

The attached patch fixes this by passing KYUA_PLATFORM to configure from
debian/rules.


An alternate fix might be to determine the architecture from the
compiler or other userspace utility that is independent from the kernel,
which might be more appropriate to submit upstream.


Thanks for maintaining kyua!


live well,
