Help : warnings when build uclibc for mips

[Amker.Cheng]

Hi:
      I am currently building uclibc-0.9.30 using gcc-3.4.4 for
mips-linux, and encountering following warnings:

> libc/sysdeps/linux/mips/clone.S: Assembler messages:
> libc/sysdeps/linux/mips/clone.S:122: Warning: No .frame pseudo-op used in PIC code
> libc/sysdeps/linux/mips/clone.S:75: Warning: Pretending global symbol used as branch target is local.

> libc/sysdeps/linux/mips/crt1.S: Assembler messages:
> libc/sysdeps/linux/mips/crt1.S:134: Warning: No .cprestore pseudo-op used in PIC code

Somebody may found these warnings before, But I could not find any
explanation or solutions

So, Could anyone help? Thanks in advance.
