configure.in: Set with_gnu_as, with_gnu_ld, with_newlib earlier.
2006-01-26 Paolo Bonzini <bonzini@gnu.org> * configure.in: Set with_gnu_as, with_gnu_ld, with_newlib earlier. Set md_exec_prefix. Use ACX_CHECK_INSTALLED_TARGET_TOOL to find the assembler, linker and binutils. * configure: Regenerate. 2006-01-26 Paolo Bonzini <bonzini@gnu.org> * config/acx.m4 (NCN_STRICT_CHECK_TARGET_TOOLS): Test $with_build_time_tools.
