This is not needed on amd64. However, several hundred + ports do not currently respect LDFLAGS, so this support is disabled currently + as it causes build failures if a dependency is looking for the stack_chk + symbols. + + [1] http://svnweb.freebsd.org/base/head/lib/libc/libc.ldscript?revision=251668&view=markup + 20130919: AUTHOR: gahr@FreeBSD.org |
