Subject: Install the SIGILL handler everywhere so we get consistent
X-Git-Tag: svn/VALGRIND_3_11_0~90
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7678f91cd1c9602217afb2f821bb16585e692cbe;p=thirdparty%2Fvalgrind.git

Install the SIGILL handler everywhere so we get consistent
stacks and don't have to worry about __GLIBC_PREREQ not being
defined on all platforms.
