Don't pass -Wl,--no-undefined to host targets

Browse Source 
Host builds were compiling without -Wl,--no-undefined because of an ASAN
issue.  Pass -Wl,--no-undefined for host builds unless sanitzers are
enabled.  Also fix LOCAL_ALLOW_UNDEFINED_SYMBOLS on darwin, where
disallowing undefined symbols is the default.

Test: m -j host
Test: m -j SANITIZE_HOST=address host
