[PATCH evemu v2 1/4] configure.ac: add '--disable-tests' option

[Peter Seiderer]

For toolchains without c++ support add option to disable
tests, because this is the only place c++ is needed (to
test the c++ binding).

Signed-off-by: Peter Seiderer <ps.report at gmx.net>

Changes v1 -> v2:
  - use BUILD_TESTS conditional (as suggested by Peter Hutterer)
