of course this is not true because of
the tls optimization bug i was fixing.

which means on other targets that don't
use optimizations there is extra 512
bytes in the test which happens to be
exactly 32*16 by which you reduced the
available static tls, so other targets
pass the test either way (with or
without reducing LIBC_IE_TLS)

but if i remove that 512byte slack from
the test then it would be visible that
you introduced a regression on all targets.
