Since [1], gcc contains a workaround for struct_kernel_stat_sz
definition and apply a local patch when updating libsanitizer with
upstream (llvm-project) [2].
Since gcc 12, the workaround is not enough and trigger the following
error:
In file included from ../../../../libsanitizer/sanitizer_common/sanitizer_platform_limits_linux.cpp:21:
../../../../libsanitizer/sanitizer_common/sanitizer_platform_limits_linux.cpp:75:38: error: static assertion failed
75 | COMPILER_CHECK(struct_kernel_stat_sz == sizeof(struct stat));
| ~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~
Disable libsanitizer for now.
Note: Only glibc toolchains are affected since libsanitizer is
disabled for musl and uClibc-ng toolchains [3].
