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.
