Use source files which have makedoc markup, but aren't processed or included.newlib-snapshot-20150623

These source files have makedoc markup, but aren't listed to be chewed by
makedoc. I am assuming that is accidental.

Future work: Note that stdio/fseeko.c, stdio/ftello.c and common/s_isnand.c have
makedoc markup, but duplicate stdio/fseek.c, stdio/ftell.c and common/s_isnan.c
respectively.
