Make memalign print useful messages on failure
Brevity is the soul of wit, except for error messages;
then it's a sign of witlessness. I can say this because
this error message may be my fault, although it is lost
in the 20th century code base so who knows.
Anyway, when memalign dies, it's not a bad idea to have
a lot of information about what went wrong. So instead
of the terse single bit of "something failed" this patch
changes things to be a bit more useful.
