MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit From: Vinson Lee <vlee@xxxxxxxxxxx> commit 4e31050f482c02c822b150d71cf1ea5be7c9d6e4 upstream. The token STT_GNU_IFUNC is not available with glibc 2.9 and older. Define this token if it is not already defined. This patch fixes this build errors with older versions of glibc.
