[Qt-creator] tool chain detection problem on FreeBSD

[HU Dong]

Hi, everyone!
    I'm using qt creator 2.5.0 on FreeBSD 9.0 release i386. When I started
qt creator after installation, I found it failed to automatically detect
tool chains, with no items in Tools->Options->Build & Run->Tool Chains. So
I added Clang (/usr/bin/clang(ver 3.0) and /usr/local/bin/gdb(ver 7.4))
with mkspec freebsd-clang. It automatically detected the correct ABI
version. Everything seemed fine until I found that the GDB debugger didn't
work properly. It simply skipped all breakpoints so that it was impossible
to trace the code(I was sure I had chosen debug build target and the binary
file it generated could be debugged manually without any problem). Then I
tried to debug the binary file using Debug->Start Debugging->Start and
Debug External Application. I was surprised to see that the tool chain
section is empty and not editable. So I think there must be some problem
with tool chain detection. Now what can I do?

    Here's toolChains.xml:
$cat .config/Nokia/toolChains.xml
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE QtCreatorToolChains>
