fd161d860f Define various symbols conditionally in shared libraries
The values of symbols in shared libraries like _end, _edata, and
__bss_start are generally not that useful outside of the shared
library.  This patch defines them conditionally with PROVIDE, since a
shared library might need the local value.  An example is glibc ld.so
local access to "_begin", "_etext" and "_end".  (ld.so gains access to
the local values by making the references using hidden visibility.
That makes the definitions hidden too.)

We can't use PROVIDE_HIDDEN in the linker scripts because the shared
library might need the value of the symbol in the executable.  An
example is freebsd libc dynamic access to "_end".

f2731e0c37 PR22829, objcopy/strip removes PT_GNU_RELRO from lld binaries
lld lays out the relro segment differently to GNU ld, not bothering to
include the first few bytes of .got.plt and padding out to a page at
the end of the segment.  This patch teaches binutils to recognize the
different (and somewhat inferior) layout as valid.

bab55c0522 Support different ld --hash-style in the ld testsuite
When ld is running with something other than --hash-style=sysv by
default, numerous tests need tweaking.  Most of the changes just add
--hash-style=sysv.  I didn't want to make --hash-style=sysv global as
that means --hash-style=gnu isn't well tested.

The original test output expectations cause it to fail when configure

43a8475ca0 Adjust LOAD segment to generate GNU_RELRO segment
This patch fixes 2 GNU_RELRO segment bugs:

1. lang_size_sections didn't properly align base to the maximum
alignment power of sections between DATA_SEGMENT_ALIGN and
DATA_SEGMENT_RELRO_END.
2. ld failed to adjust LOAD segment to generate GNU_RELRO segment
when LOAD segment doesn't fit GNU_RELRO segment.  This is

https://sourceware.org/bugzilla/show_bug.cgi?id=14207

We "fixed" ld by not generating GNU_RELRO segment.  This patch
adjusts LOAD segment to generate GNU_RELRO segment.  It fixes
PR ld/16322 and at the same time it also fixes PR binutils/16323
since now we can adjust LOAD segment if it is too small.
