It fails to compile pseudo-native on centos 7:
| ports/linux/pseudo_wrappers.c: In function ‘prctl’:
| ports/linux/pseudo_wrappers.c:129:14: error: ‘SECCOMP_SET_MODE_FILTER’
undeclared (first use in this function)
| if (cmd == SECCOMP_SET_MODE_FILTER) {
| ^
Add macro guard for the definition to avoid the failure.
