Automatic makefile dependencies for generated ld/e*.c
This patch modifies genscripts.sh to emit dependency info along with
the generated emulation e*.c files. This is done by a new source_sh
function that records its arg to a file (.deps/e*.Tc), using the
function whenever a shell script is sourced. Entries in the file are
made unique and written to .deps/e*.Pc. These files are then
included by the Makefile.
* Makefile.am (GENSCRIPTS): Pass LIB_PATH as a parameter. Add
DEPDIR parameter.
(ELF_DEPS, ELF_GEN_DEPS, ELF_X86_DEPS): Delete.
(ALL_EMULATION_SOURCES, ALL_64_EMULATION_SOURCES): Depend on
$GEN_DEPENDS.
(e*.c): Delete all dependencies, instead include dependencies
from $DEPDIR/*.Pc.
* Makefile.in: Regenerate.
* configure.ac (source_sh): Define and use function.
* configure: Regenerate.

Reorder more powerpc64 sections for -z relro
This moves .got too, which requires .sdata and .sbss to move with it,
because these sections share addressing via the toc pointer and with
small-model code must be within a 16-bit signed offset. .plt, .iplt
and .branch_lt must also be moved since they are addressed via a
32-bit offset from the toc pointer, and we might have a very large
.data section.
This change means we may have some bss style sections before the data
segment, necessitating another PT_LOAD header. Also, since _edata is
defined at the end of the data segment it's possible with an empty
.data to have _edata at the end of .plt which looks a little unusual
since .plt is a bss style section. That should only happen rarely in
real world binaries, but does occur in the ld testsuite.
