We are trying to link a 3rd party library compiled using the ARM/IAR compiler
into our project, which we compile using the GNU arm-elf toolchain. ld fails to
link the 3rd party library, and spits out warnings: "warning: internal error:
unsupported relocation error"
The ld appears to be complaining because the IAR compiler produces instructions
which must be relocated using R_ARM_THM_PC8, but it appears that R_ARM_THM_PC8
isn't implemented in binutils. I was able to confirm this by recompiling
binutils with some printf statements describing the unsupported relocation
method.
