I wasn't speaking about autoconf, that never works for kernel support.

I was afraid that tst_brk() from tst_syscall() would exit the whole
test, but it looks like the test library is smart enough and it does not
set the abort_flag for TCONF and the test will continue running
even if one of the variants called tst_brk(TCONF, ...). So I suppose
that the test actually runs correctly on kernel that does not support
open_tree_attr() even with -i 10.
