gnu tool-chain support for mips16?

Dear all:

I follow rules on http://www.ltc.com/~brad/mips/mips-cross-toolchain/
to build gnu tool-cahin. 
It works pefect for me to build linux/glibc/ulibc, and perform excellent on my Demo Board.

However, it report some bug messags as following when I compile a test.c 
like:
int test()
{
    return 0;
}

===================
mips-linux-gcc -c -mips16 -o test test.c
/tmp/ccjnCwV7.s: Assembler messages:
/tmp/ccjnCwV7.s:14: Internal error!
Assertion failure in macro_build_lui at ../../gas/config/tc-mips.c line 3107.
Please report this bug.

Can you kindly give me some help in this? 
Thank you very much.

All userspace with glibc, the standard userspace library environment for
Linux, must be PIC code and therefore the Linux compiler defaults to PIC
It's not possible to combine PIC code and MIPS16 ...
