cmake: fail on unknown attribute

on Clang, the option for detecting unknown attribute is
-Wunknown-attributes, so "-Wattributes -Werror" does not fail the test
when the C compiler is Clang.

in this change, we just turn all warnings into errors.
this should fail the test if the compiler does not understand
`__attribute__((__symver__ ...))`
