lttng-ust: fix do_compile failure for arm32 with DEBUG_BUILD enabled

Browse Source 
After upgrade to 2.13.0, for arm32, with DEBUG_BUILD enabled, lttng-ust
build failed with error:
| /path/to/tmp/work/cortexa15t2hf-neon-poky-linux-gnueabi/lttng-ust/2_2.13.0-r0/recipe-sysroot-native/usr/bin/arm-poky-linux-gnueabi/../../libexec/arm-poky-linux-gnueabi/gcc/arm-poky-linux-gnueabi/11.2.0/ld: ../../../src/lib/lttng-ust/.libs/liblttng-ust.so: undefined reference to `_uatomic_link_error'
| collect2: error: ld returned 1 exit status
| Makefile:399: recipe for target 'test_ust_error' failed
| make[3]: *** [test_ust_error] Error 1

The problem has reported to upstream, and upstream suggests to use
-DUATOMIC_NO_LINK_ERROR for the failure case, refer [1].
