[Buildroot] Buildroot toolchain for arm

[Chia-Hung Chou]

I want to build the toolchain to compile into fully thumb instruction. In
the menuconfig, I add the "--with-mode=thumb" into gcc options.
After I make the buildroot, there are some Errors :
    make[5]: *** [libmudflap.la] Error 1
    make[5]: Leaving directory
'/home/chiahung/buildroot-2011.02/output/toolchain/gcc-4.4.5-final/arm-unknown-linux-uclibic/libmudflap'
    make[4]: *** [all-recursive] Error 1
    make[4]: Leaving directory
'/home/chiahung/buildroot-2011.02/output/toolchain/gcc-4.4.5-final/arm-unknown-linux-uclibic/libmudflap'
    make[3]: *** [all] Error 2
    make[3]: Leaving directory
'/home/chiahung/buildroot-2011.02/output/toolchain/gcc-4.4.5-final/arm-unknown-linux-uclibic/libmudflap'
    make[2]: *** [all-target-libmudflap] Error 2
    make[2]: Leaving directory
'/home/chiahung/buildroot-2011.02/output/toolchain/gcc-4.4.5-final'
    make[1]: *** [all-target-libmudflap] Error 2
    make[1]: Leaving directory
'/home/chiahung/buildroot-2011.02/output/toolchain/gcc-4.4.5-final'
    make: ***
[/home/chiahung/buildroot-2011.02/output/toolchain/gcc-4.4.4.5-final/.compiled]
Error 2
 I try a lot of ways but I still can't solve it. Is there any way to solve
or to build a toolchain that could compile code into fully thumb
instruction??

thanks~
