Hi,
is there any particular reason not to install the address sanitizer with gcc-libs?
The issue referenced in the commit that removed it can't be accessed anymore, so I have no idea why you removed it:

It's really annoying not to have libasan.so in ALARM, it looks like only the library isn't included in the package, compiling with -fsanitize=address gives the expected result, only linking to libasan fails. Other distros have it since gcc 4.8 on ARM, so it should be possible with Archlinux too.
Regards,
