[Qemu-devel] [RFC PATCH] tests/tcg: add write tests for nbyte = 0

["Carlo Marcelo Arenas Belón" <carenas@gmail.com>]

rename linux-test so we can get both (32 and 64 bit) versions in a multilib
x86 host.

published as an RFC since the include options that were needed to fix the
build will most likely conflict with scripts/clean-includes

`make check` is unaffected by this new test (which fails in x86_64) and the
rule to automatically run it against qemu-user and diff has been left out
in purpose, not to affect any user of the remaining surrounding tests, but
discussion on how to get tests/tcg back in shape, or if linux-user should
be tested somewhere else is also encouraged
