generalize mips-specific reloc code not to hard-code sym/type encoding

this change is made in preparation for adding the mips64 port, which
needs a 64-bit (and mips64-specific) form of the R_INFO macro, but
it's a better abstraction anyway.

based on part of the mips64 port patch by Mahesh Bodapati and Jaydeep
Patil of Imagination Technologies.
