Subject: Don't scan for valgrind at configure time
X-Git-Tag: v1.10~10
X-Git-Url: http://git.vpit.fr/?p=perl%2Fmodules%2FTest-Valgrind.git;a=commitdiff_plain;h=5ee5c767e23b5c9c7660a2a0fda30962ef924d65

Don't scan for valgrind at configure time

We don't need this anymore since suppressions are now generated on the fly.
This removes almost all configure_requires dependencies.
The module ought to handle systems where valgrind is not present anyway.
