gcc: fix hidden weak symbols by removing buggy gcc patch
We are noticing the presence of the following patch in various openembedded gcc versions: 0024-PR-target-32219.patch However, contrarily to its "Backport" status, that patch is not upstream in gcc, and it breaks handling of start/stop automatic weak hidden symbols we use in lttng-ust. We are only experiencing problems on the various openembedded compilers, but on no other distro (with same compiler versions), which led us to suspect a buggy distro-specific gcc patch. We've been testing with openembedded gcc-4.9.2-r0. Rebuilding the gcc compiler with this patch removed fixes the lttng-ust issue.
