Add a temporary hack to let BoringSSL build with a new compiler.

This change causes BoringSSL's asm code to unconditionally use a
HWASAN-compatible global variable reference so that the non-HWASANified
(because of sanitize: { hwaddress: false } above) code in the BCM can
successfully link against the HWASANified code in the rest of BoringSSL in
HWASAN builds.
