gcc-runtime: Make DEBUG_PREFIX_MAP relative to S

Current definition of SLIB is actually equal to S but is hardcoded, this
means when we have altered location of S, then the regexp for
DEBUG_PREFIX_MAP will not be effective, which could result in S being
emitted into debug_line sections. Simplify the maps to use S variable
instead of SLIB

Secondly, rename SLIB_NEW to REL_S to make it more appropritate to what
it represents
