openrisc: Add R_OR1K_32_PCREL relocation type module support

Browse Source 
To ensure the proper functioning of the jump_label test module, this patch
adds support for the R_OR1K_32_PCREL relocation type for any modules. The
implementation calculates the PC-relative offset by subtracting the
instruction location from the target value and stores the result at the
specified location.
