[arm-gnu] Linking error in arm-none-linux-gnueabi toolchain

[Umar Qureshey]

Hi,
I am trying to compile using 

arm-none-linux-gnueabi-gcc (Sourcery CodeBench Lite 2012.09-64) 4.7.2

I am getting linking errors upon issuance of this command:

All these symbols resolve within libgcc or thereabouts because I checked with nm but don't know why the linker is unable to find.

Not sure if this'll help but the object code is compiled with:

make CFLAGS="-D__KERNEL__ -I/home/umar/iradt/arm-linux/include -Wall -Wstrict-prototypes -Wno-trigraphs -O2  -fno-strict-aliasing -fno-common -fno-builtin-sprintf -Wno-packed -Wno-pointer-sign -fno-common -pipe  -march=armv4 -mtune=arm7tdmi -msoft-float " -C  arch/arm/lib

Thanks & Regards,
