rtems gcc 4.6.1 can not compile stop at check TLS

[Xiangfu Liu]

Hi

I have tried compile lm32-rtems-gcc 4.6.1 with:
  ubuntu 11.04 64bit with gcc-core-4.6.1-rtems4.11-20110621.diff
  ubuntu 11.04 64bit with gcc-core-4.6.1-rtems4.11-20110715.diff
    $ gcc --version
    gcc (Ubuntu/Linaro 4.5.2-8ubuntu4) 4.5.2


  debian 6 32bit with gcc-core-4.6.1-rtems4.11-20110621.diff
  debian 6 32bit with gcc-core-4.6.1-rtems4.11-20110715.diff
    $ gcc --version
    gcc (Debian 4.3.2-1.1) 4.3.2


all of them stop at: "checking whether the target assembler supports thread-local storage... "
then 'cc1' eat all memories and swap. system became very very slow then.

do I have to update my system gcc to 4.6.1? any help will be great.

thanks in advance.
