Dear Axel Lin,

Are you sure uclinux as TARGET_OS is the right selection for ARM? The
release notes of gcc 4.7, at http://gcc.gnu.org/gcc-4.7/changes.html,
indicate:

""
The obsolete ports with alternatives are:

    arm*-*-rtems (use arm*-*-rtemseabi)
    arm*-*-linux-gnu (use arm*-*-linux-gnueabi)
    arm*-*-elf (use arm*-*-eabi)
    arm*-*-uclinux* (use arm*-*-uclinux*eabi)
""

So it looks like the arm-<something>-uclinux* tuple should not be used,
if I understand this correctly. Do you have more details about why
arm-<something>-uclinux* should be used?

Thanks!

Thomas
