There is (undocumented) library helper tst_get_bad_addr() which might bring some
arch portability.

BTW: Looking into this, which I merged in 63f8a3f77 ("sigpending: use direct
syscall") removed testing sigpending() glibc wrapper from intel. Now:
sigpending02.c:67: CONF: syscall(-1) __NR_sigpending not supported
@Cyril, is it ok for us?
I guess, we should do something about #506 [1] to solve problems like this.

I'd join this string. + trailing space after got.
