adb: Don't force -O2

Don't force -O2 over -O3 -- the O2 hardcode is there to force
optimizations, not to reduce them...

sync_test: Use -fno-strict-aliasing

Use -fno-strict-aliasing here so we don't have to use it globally.
Performance on tests isn't important anyway.

corkscrew-x86: Fix build with some glibc versions

Make sure __USE_GNU is actually set before ucontext.h is included
(even implicitly).

adb: Link to libdl manually to avoid build failure on android-build

An outdated build environment results in a host adb build failure
because libcrypto needs libdl, but libdl isn't linked explicitly:

corkscrew: Fix build with gcc 4.8

gcc 4.8 has a new warning for unused parameters - we need to override
-Werror on that.
