[U-Boot] "raise" not defined, when compiler uses its own div0

When trying to build U-Boot under Buildroot and OpenEmbedded, I run into a problem:

When linking u-boot the linker seems to use the div0 from the C compiler libgcc instead of the u-boot div0.

gcc div0 for ARM contains a call to "raise" which is not defined in libgcc.a (someone said it was part of glibc), so the linking process fails due to no "raise" symbol

gcc/config/arm/lib1funcs.asm contains:

FUNC_START div0

tmfd sp!, {r1, lr} mov r0, #SIGFPE bl SYM(raise) __PLT__ ...

The problem can be fixed by patching the C compiler:

+ bl SYM(raise) __PLT__ + bl SYM(_div0) __PLT__

------ What I'd like to know: Is there a way to fix this in u-boot?

Tried creating a "raise" function in libarm/board.c void raise(void) { hang(); }

which did not work.

I later saw that raise needs a parameter, but it complained that raise is not found, and not that the parameters is wrong.

Is board.c not included in the link?

Anyone else got this problem?
