Remove -fforce-addr from the default CFLAGS.

This flag breaks clang, which does not support it, and is obsolete
 on gcc anyway.

Fix mismatched oc_mb_fill_cmapping11 signature.

oc_mb_fill_cmapping11() was defined without the last two parameters
 of its fellow mapping functions, meaning it got called with extra
 undeclared parameters.

This could confuse the emscripten JavaScript cross-compiler's asm.js
 optimizations, as it's very picky about function signatures.

Fixes #2068.
