* Makefile.am (eelf32iq10.c): Fix tab/whitespace mixup.
* Makefile.am (ldmain.o): Add @TARGET_SYSTEM_ROOT_DEFINE@.
(GENSCRIPTS): Add @use_sysroot@.
* Makefile.in: Regenerated.
* configure.host: Move setting of NATIVE_LIB_DIRS to...
* configure.tgt: ... here. Use ${target} instead of ${host}
for NATIVE_LIB_DIRS.
* configure.in: Add --with-sysroot.
* configure: Regenerated.
* genscripts.sh: Accept use_sysroot option. Set new variables
NATIVE and USE_LIBPATH. Prepend "=" to directory names if
$use_sysroot. Don't search $tool_lib if $use_sysroot.
* ldfile.c (ldfile_add_library_path): Handle leading '='.

searching $EMULATION_LIBPATH.
(gld${EMULATION_NAME}_add_sysroot): New function.
(gld${EMULATION_NAME}_check_ld_so_conf): Use it. Honor ld_sysroot.
(gld${EMULATION_NAME}_after_open): Likewise. Only search
environment variables if $NATIVE.
