[Android] Temporarily disable --warn-shared-textrel for mips

Temporarily disable the warning until a permanent solution can be found.

thakis@: PTAL. Dirty, but at least it will unblock downstream mips builds while
still preserving --fatal-warnings otherwise. Tested locally.

Is it understood what exactly is being warned about? I feel a bit uneasy about
suppressing an error we don't understand.

I don't understand either. It sounds like text relocations can have security
implications, so I'm happy to sit on this until we receive further word from
those in the know.

lgtm, given that danalbert says that this should be fixed in newer toolchains.
(I'll try to build with a newer ld, but no need to wait for that.) Let's land
this and reland the libc++ thing for android.
