Rich Felker 0ff18be208 fix incorrect __hwcap seen in dynamic-linked __set_thread_area 
the bug fixed in commit b82cd6c78d 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.

    musl libc

musl, pronounced like the word "mussel", is an MIT-licensed
implementation of the standard C library targetting the Linux syscall
API, suitable for use in a wide range of deployment environments. musl
offers efficient static and dynamic linking support, lightweight code
and low runtime overhead, strong fail-safe guarantees under correct
usage, and correctness in the sense of standards conformance and
safety. musl is built on the principle that these goals are best
achieved through simple code that is easy to understand and maintain.

The 1.1 release series for musl features coverage for all interfaces
defined in ISO C99 and POSIX 2008 base, along with a number of
non-standardized interfaces for compatibility with Linux, BSD, and
glibc functionality.

For basic installation instructions, see the included INSTALL file.
Information on full musl-targeted compiler toolchains, system
bootstrapping, and Linux distributions built on musl can be found on
the project website:
