From 2e1a87a3e11b6928b128fcf72570178a250ba072 Mon Sep 17 00:00:00 2001 From: Jo-Philipp Wich Date: Mon, 24 Jul 2017 13:33:33 +0200 Subject: [PATCH] build: bundle-libraries.sh: do not override argv[0] in inner exec calls Only mangle argv[0] of the first executed process and leave the argument vector of subsequent invocations as-is to allow child programs to properly discover resources relative to their binary locations. Fixes "cc1" discovery when executing the host gcc through the bundled "ccache" executable.
