feature-test: add CONFIG_COMPAT compile option
I'll wrap all compatible code in this CONFIG_COMPAT define.
As I'll wrap also compatible parasite generation in this,
it's also makefile variable, rather than just C define.
The test itself consists of including stubs-32.h, which is
glibc6-i686 presence test and is compiled with -m32 option,
which is test for gcc-multilib.
