[Linaro-uefi] "aarch64-none-elf-ar" has command line string size limit??

Hi,

I am working on compile a UEFI project for AARCH64 platform on a Windows 7 machince using the following toolchain.

http://releases.linaro.org/14.09/components/toolchain/binaries/gcc-linaro-aa...

Now everything compiles except the last step of using "aarch64-none-elf-ar". We have about 100 obj files (say from OBJ#001 to OBJ#100) and "aarch64-none-elf-ar" reported "OBJ#50 file is missing".

It seems to me that "aarch64-none-elf-ar" has a limit of the command line string size.I tried to shorten the directory name (and file name), the situation got improved a little bit, now "aarch64-none-elf-ar" reports ""OBJ#85 is missing".

Does anyone is there a such limit and how could we circumvent this problem?

Thanks Jianning
