Summary:
Unlike the rest of the sanitizer code, lib/interception uses native macros like __linux__
to check for specific targets instead of the common ones like SANITIZER_LINUX.
When working on the Solaris port of the sanitizers, the current style was found to not
only be inconsistent, but clumsy to use because the canonical way to check for Solaris
is to check for __sun__ && __svr4__ which is a mouthful.
Therefore, this patch switches to use SANITIZER_* macros instead.
Tested on x86_64-pc-linux-gnu.

This fixes a crash in pthread_create on linux/i386 due to abi
incompatibility between intercepted and non-intercepted functions.
See the test case for more details.

libpthread is weird:
/lib/x86_64-linux-gnu/libpthread.so.0:000000000000b9b0 T pthread_cond_init@@GLIBC_2.3.2
/lib/x86_64-linux-gnu/libpthread.so.0:000000000000c720 T pthread_cond_init@GLIBC_2.2.5
let's do it with @@ for now
we can always introduce more macros parameters later

The idea isthat asan/tsan can survive if user intercepts the same functions. At the same time user has an ability to call back into asan/tsan runtime. See the following tests for examples:
asan/output_tests/interception_failure_test-linux.cc
asan/output_tests/interception_test-linux.cc
asan/output_tests/interception_malloc_test-linux.cc
