libthr: Preresolve selected EABI symbols on arm.

Add the ability to pre-resolve architecture-specific EABI symbols and
use it on arm for selected EABI functions. These functions can be called
with rtld bind lock write-locked, so they should be resolved in forward.

Remove PAGE_SIZE from libthr

In libthr we use PAGE_SIZE when allocating memory with mmap and to check
various structs will fit into a single page so we can use this allocator
for them.

Ask the kernel for the page size on init for use by the page allcator
and add a new machine dependent macro to hold the smallest page size
the architecture supports to check the structure is small enough.

This allows us to use the same libthr on arm64 with either 4k or 16k
pages.

libthr: Use <machine/tls.h> for most MD TLS details.

Note that on amd64 this effectively removes the unused tcb_spare field
from the end of struct tcb since the definition of struct tcb in

This macro is confusing as it is not related to the similarly named
