Unfortunately, this doesn't work:


configure:3276: checking whether the C compiler works
configure:3298:
/opt/freescale/usr/local/gcc-4.1.2-glibc-2.5-nptl-3/arm-none-linux-gnueabi/bin/arm-none-linux-gnueabi-gcc
-std=gnu89 -g -ffast-math -fsingle-precision-constant
-mpic-register=r11 -fPIC -DPIC conftest.c >&5
conftest.c:1: error: unable to use 'r11' for PIC register
configure:3302: $? = 1
configure:3340: result: no

The same happends with r12 register. Registers r1-10 are used directly
in the assembly.
