[sheepdog] [PATCH v2 07/10] configure: support tracer with debug build

[MORITA Kazutaka]

From: MORITA Kazutaka <morita.kazutaka at lab.ntt.co.jp>

Now we can use tracer with debug build.  This patch enables it by
default when --enable-debug is specified.  Let's see whether it should
be enabled in the release build too.
