Many ports (m32r, microblaze, mips, parisc, score, and sparc) use functionally identical copies of various GCC library routine files, which came up as we were submitting the RISC-V port (which also uses some of these). This patch adds a new copy of these library routine files, which are functionally identical to the various other copies. These are availiable via Kconfig as CONFIG_GENERIC_$ROUTINE, which currently isn't used anywhere.
