Some powerpc machines can support 64k pages, enabled by the
CONFIG_64K_PAGES option in linux.
However, the uClibc dynamic loader won't currently work on these
machines, as it uses hard-coded values (PAGE_ALIGN, ADDR_ALIGN and
OFFS_ALIGN) in the ldso architecture-specific headers. When running on
a kernel with 64k pages, ld.so tries to mmap with 4k-aligned addresses,
rather than 64k, so mmap fails with -EINVAL.
When booting a 64k machine with a uClibc dynamic linker, init fails
with:
/init:500: can't map '/lib/libc.so.0'
/init:500: can't map '/lib/libc.so.0'
/init:500: can't map '/lib/libc.so.0'
/init: can't load library 'libc.so.0'
Kernel panic - not syncing: Attempted to kill init!
This change allows ld.so determine these alignment masks at runtime,
rather than compile-time. Since we have the _dl_pagesize variable
available, we can use that to generate the appropriate masks.
Since almost all of the architectures can use the common definitions for
the _ALIGN macros, we can consolidate them all in ldso.h, and override
in the sysdep headers where necessary (ie, mips).
This allows me to start a uClibc-based root fs on a 64k machine.

while keeping WCHAR support enabled. This solves two
testcases: tst_wcwidth and tst_wcswidth.
Fix dat_iswctype.c fiinput file: character 0x80 is not
a control character: it fixes tst_iswctype test.

better document what's going on in sigaction().
seems to not induce any actual code changes (sans mips).

Thanks to Skinkie for noticing.

This patch fixes position-independent executables (PIEs) for Thumb-2. In
Thumb assembly, instructions reading pc give a value 4 greater than the
address of the instruction, rather than 8 greater as in ARM mode, so the
offset to the GOT needs to have the right offset. (The Thumb-1 code
already gets this right; it's the code shared by ARM and Thumb-2 that
needs fixing.)
