--- Comment #1 from Adrian Perez <aperez at igalia.com> ---
The easy way to go about this would be detecting whether <valgrind.h>
is available, and use the “RUNNING_ON_VALGRIND” macro defined by it:

  http://valgrind.org/docs/manual/manual-core-adv.html#manual-core-adv.clientreq

Note that it expands to inline assembler in the architectures supported
by Valgrind, so it would be a build-time dependency only. It would be
nicer to not need Valgrind for building, but other alternative I see
around is checking “/proc/self/smaps” and grep for the name of the
Valgrind shared library which gets LD_PRELOAD'ed and that looks flimsy
to me.
