From d268ab32e3136534e8a1dd7e53eafd3583aea15a Mon Sep 17 00:00:00 2001 From: Alexander Couzens Date: Mon, 13 Apr 2015 17:15:12 +0200 Subject: crossgcc: close stdin when search_tool() execute programs. bzip2 --version |grep -c will wait for input on stdin. ./buildgcc will hang because of this. Add `cat /dev/null |` close the stdin.
