configure.in (mips*-*-*): Add a test to see if MIPS libgloss linker scripts use STARTUP directives... 

2002-07-29  Chris Demetriou  <cgd@broadcom.com>

        * configure.in (mips*-*-*): Add a test to see if MIPS libgloss
        linker scripts use STARTUP directives consistently.
        * configure: Regenerate.
        * config.in: Regenerate.
        * config/mips/elf.h (STARTFILE_SPEC): Define conditionally, based
        on whether HAVE_MIPS_LIBGLOSS_STARTUP_DIRECTIVES is defined.
        * config/mips/elf64.h (STARTFILE_SPEC): Likewise.
        * config/mips/isa3264.h (STARTFILE_SPEC): Do not redefine if
        HAVE_MIPS_LIBGLOSS_STARTUP_DIRECTIVES is set; the result
        will be the same.
