Set -DUATOMIC_NO_LINK_ERROR as suggested by upstream in
https://www.mail-archive.com/lttng-dev@lists.lttng.org/msg12950.html to
avoid the following build failure with lttng-tools raised since bump to
version 2.13.1 in commit 733bf73e3ff86dd80e68e22c0ccc2f43e4a3d475:
/home/buildroot/autobuild/instance-1/output-1/host/opt/ext-toolchain/bin/../lib/gcc/mips64el-buildroot-linux-gnu/9.3.0/../../../../mips64el-buildroot-linux-gnu/bin/ld: /home/buildroot/autobuild/instance-1/output-1/host/mips64el-buildroot-linux-gnu/sysroot/usr/lib/liblttng-ust-ctl.so: undefined reference to `_uatomic_link_error'
Fixes:
