Move the check if arm-mem should be included from virtual/libc
to config/options and set the ARM_MEM_SUPPORT variable accordingly.
This makes it possible to opt-out of using arm-mem which can
be helpful for performance testing and debugging (eg valgrind
doesn't play nicely with it).

ARMv8.0-A cpus have an optional LSE feature. This is mandatory in
ARMv8.1-A. By default, gcc will attempt to build support for runtime
detection of the LSE feature on ARMv8.0-A. This causes build failures
when attempting to create a 64-bit userland.
Test packages for this failure include gdb and mesa. Errors manifest
as undefined references to "__aarch64_cas4_acq_rel" or
"__aarch64_swp4_acq_rel" at compile time.
Disable runtime detection to always use its fallback by adding
-mno-outline-atomics to cflags.
