We weren't applying applying the libdir subdir to header directories but this
is necessary for corretness when building e.g. ASan variant. This change also
updates path construction logic accross all runtimes and ensures they're
consistent.

Subject: [PATCH] [runtimes] Correctly apply libdir subdir for multilib
We weren't applying applying the libdir subdir to header directories
but this is necessary for corretness when building e.g. ASan variant.
This change also updates path construction logic accross all runtimes
and ensures they're consistent.
