This is because MB_CUR_MAX is part of ANSI C + amendment 1 (ca. 1995), and
no platforms are known that lack it (see gnulib/doc/posix-headers/stdlib.texi).
Likewise for mbtowc(): It's present on all platforms we care about, see
gnulib/doc/posix-functions/mbtowc.texi.

There is an easy way out: just don't disable all multibyte related stuff
in uClibc.
uClibc has this code, that's what you're saying. Therefore there's no point
in gnulib to duplicate this functionality. All other platforms have
ANSI C + amendment 1.

No, gnulib is not providing the whole locale and multibyte layer from
scratch. It provides the reasonable set of multibyte functions, assuming
the foundations are already implemented in the system libc.
