For the same reasons as for ASAN we have to avoid using the HWASAN
sanitizer when compiling libiberty and the lto-plugin.
Also add a function to query whether -fsanitize=hwaddress has been

I'm fine, thanks Sara

Hi Matthew,
Martin is the authority on this but I have a small comment inline...

For the same reasons as for ASAN we have to avoid using the HWASAN
sanitizer when compiling libiberty and the lto-plugin.
