uClibc does have locale support (new feature). On the other hand,
most binaries compiled against a "modern" Glibc (2.2.x) are not
compatible with the old Glibc used in LEAF (my experience, maybe I
did something wrong :-). So to create binaries for LEAF I needed an
old Linux distribution with Glibc2.0, for uClibc I just installed the
development environment on my 'modern' distribution.
