gcc-sanitizers: fix -Werror=maybe-uninitialized issue
When DEBUG_BUILD = "1" added in local.conf, there
comes below build error when "bitbake gcc-sanitizers":
| ./../../../../../../../../work-shared/gcc-8.3.0-r0/gcc-8.3.0/libsanitizer/libbacktrace/../../libbacktrace/elf.c: In function 'elf_is_symlink':
| ../../../../../../../../../work-shared/gcc-8.3.0-r0/gcc-8.3.0/libsanitizer/libbacktrace/../../libbacktrace/elf.c:772:21: error: 'st.st_mode' may be used uninitialized in this function [-Werror=maybe-uninitialized]
| return S_ISLNK (st.st_mode);
After commit[16643b0322 bitbake.conf: Use -Og in DEBUG_OPTIMIZATION]
introduced, "-Og" added to compiler when debug
build enabled.
Per https://gcc.gnu.org/ml/gcc-patches/2019-04/msg00315.html,
the gcc upstream thinks the warning is a false
positive and suggests to use -O2 rather than -Og
or -O1 when compiling that file, so pass -Wno-error
to compiler when -Og is used to silence the error.
