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.
