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.
