From f8be4231f82ab56a87ce74906671afbe1aa9ec75 Mon Sep 17 00:00:00 2001 From: Tom Zanussi Date: Mon, 30 Nov 2009 01:18:46 -0600 Subject: [PATCH] perf trace/scripting: Silence PERL_EMBED_* backtick errors The backtick shell substitutions for PERL_EMBED_LDOPT/CCOPT make a lot of noise on stderr if Embed.pm isn't installed - this silences them.
