How can I disable the default libgloss for arm when linking!

[Cliff Tsai]

Hi:

    When I link libc.a with my own libgloss.o functions,
    The multiple definition errors occured!

    When building newlib for arm.The libgloss functions(_open,_close....)
    in /libc/sys/arm/systencalls and functions in libcfunc.c will be
created.
    How can I remove the installation when building newlib for arm?
    Or how can I disable them?

Thanks!
