This can cause errors due to symbols being missed/undefined due to incorrect flags. For example, when testing compilation on Alpine linux, we got: error: unknown type name 'cpu_set_t' due to _GNU_SOURCE not being defined in the cflags. This issue can be fixed by appending "-mavx2" to the cflags rather than replacing them with it.
