src/sys/sys: cdefs_elf.h
Log Message:
Disable Address Sanitizer instrumentation of the link_set objects
The link_set array must contain consecutive elements that can be iterated.
GCC disables instrumentation of globals for user-defined sections and this
__noasan attribute is implicit for this compiler. For Clang it is required
to be specified explicitly.
