As support for RISC-V was only merged into the mainline kernel at 4.15
it is unlikely that glibc will be happy with a reported kernel version
of 3.8.0. Indeed when I testing binaries created by the current Debian
Sid compiler the tests failed with:

  FATAL: kernel too old

Bump the version to the minimum a RISC-V glibc would expect:

This link point to the last version which might change over time, can we
use instead the full link Peter suggested?
