Issues with running AddressSanitizer using Bazel toolchains

[ashelkovnykov]

Trying to enable AddressSanitizer in the current build is incredibly frustrating, and there's still no known configuration to do so.

The existing workaround is:

1. Add 'asan' config to .bazelrc:

   build:asan --strip=never
   build:asan --copt -fsanitize=address
   build:asan --copt -DADDRESS_SANITIZER
   build:asan --copt -O1
   build:asan --copt -g
   build:asan --copt -fomit-frame-pointer
   build:asan --linkopt -fsanitize=address
   

2. CC=/usr/bin/gcc-11 bazel build --force_ignore_dash_static --config asan :urbit
   1. This will fail with The above will fail with: "gcc-11: error: cannot specify -static with -fsanitize=address"
3. sudo sed -i 's//-static/' bazel-out/k8-fastbuild/bin/pkg/vere/urbit-2.params
4. /usr/bin/gcc-11 @bazel-out/k8-fastbuild/bin/pkg/vere/urbit-2.params
