Delete ASAN 
It hasn't been helpful enough to be justify the maintenance burden. What
actually does help is mprotect(), kprintf(), --ftrace and --strace which
can always be counted upon to work correctly. We aren't losing much with
this change. Support for ASAN on AARCH64 was never implemented. Applying
ASAN to the core libc runtimes was disabled many months ago. If there is
some way to have an ASAN runtime for user programs that is less invasive
we can potentially consider reintroducing support. But now is premature.

#
# DESCRIPTION
#
# This file defines the libraries, runtimes, and build rules needed to
# create executables from your Linux workstation that'll run anywhere.
# Loading this package will make certain systemic modifications to the
# build like turning off the System V "Red Zone" optimization, because
# αcτµαlly pδrταblε εxεcµταblεs need to be able to run in kernelspace.
