sparc: fix the extraction of relocation IDs from r_type fields.
This patch adds support for a RELOC_TYPE_ID transform macros that
backends can use before including common-reloc.c. The sparc backend
uses this in order to extract the relocation IDs from r_type fields.
In this target the most significative 24 bits of r_type are used to
store an additional addend in some relocation types.
