It's even worth ... it's ltib ... ;)

The problem originates from the fact that the ltib rootfs doesn't contain 
basic building blocks (e.g. crt1.o).

The ltib-freescale-linaro toolchain on the other hand does ... and finds them 
automatically based on the other options you give him (e.g. -mthumb, -mfloat-
abi=...)

So you can't use gcc's --sysroot, because then you'll overwrite the 
"automatically-finding-my-personal-toolchain-sysroot"-algorithm.

You still can use configure's -sysroot by additional using '-no-gcc-sysroot'


In the end Thiago is right anyway: wrong sysroot :)
... sysroot should point to your build-filesystem ... if you're using ltib, 
your only option is to use your rootfs.
