the bug fixed in commit b82cd6c7 was
mostly masked on arm because __hwcap was zero at the point of the call
from the dynamic linker to __set_thread_area, causing the access to
libc.auxv to be skipped and kuser_helper versions of TLS access and
atomics to be used instead of the armv6 or v7 versions. however, on
kernels with kuser_helper removed for hardening it would crash.

since __set_thread_area potentially uses __hwcap, it must be
initialized before the function is called. move the AT_HWCAP lookup
from stage 3 to stage 2b.

at least gcc 9 broke execution of DT_INIT/DT_FINI for fdpic archs
(presently only sh) by recognizing that the stores to the
compound-literal function descriptor constructed to call them were
dead stores. there's no way to make a "may_alias function", so instead
launder the descriptor through an asm-statement barrier. in practice
just making the compound literal volatile seemed to have worked too,
but this should be less of a hack and more accurately convey the
semantics of what transformations are not valid.
