Handle machine-dependent (m-d) (string) sources more automatically.

The names of m-d variants are now added (manually) to MDSRCS instead
of to SRCS, and the names of all machine-independent (m-i) variants
that can reasonably be replaced by an m-d variant are now added
(manually) to MISRCS instead of to SRCS, so that a simple substitution
can be used to discard the unused m-i variants.  MISRCS is potentially
all m-i sources, but the substitution is too simple to be fast, so
MISRCS should be kept reasonably small.

libc/Makefile.inc:
Do the substitution.

libc/i386/string/Makefile.inc:
Add to MDSRCS instead of to SRCS.  Add the names of all sources in this
directory, but no others.

libc/string/Makefile.inc
Add to MISRCS instead of to SRCS.  Add the names of all sources in this
directory.  Don't use (broken) explicit rules for special cases.
