The point wasn't to skip the test, it was to fix the bug. :-) 
Unfortunately, the CFLAGS change doesn't do that after all. If anything, 
it's worse:

./seq 9223372036854775807 9223372036854775808 | head
9223372036854775808
9223372036854775808
9223372036854775808
9223372036854775808
9223372036854775808
9223372036854775808
9223372036854775808
9223372036854775808
9223372036854775808
9223372036854775808

Before the CFLAGS change (add -mlong-double-64) it just did this:

./seq 9223372036854775807 9223372036854775808    
9223372036854775808

whereas with 8.5 it did this:

seq 9223372036854775807 9223372036854775808
9223372036854775807
9223372036854775808
