I was thinking of a test like this within the C source code:
#if defined(__GLIBC__) && __GLIBC__ == 2
#include <something>

We have this for detecting glibc 2.x. Maybe there is a similar symbol defined
for uClib? If there is, we could rely on it to automatically disable the use
of iconv. This would work for both the cross-compilation and the
chroot-environment cases.

For glibc 2.3, the symbol is defined in include/features.h. Could you please
take a look at this file (or any other you see fit) in your uClibc compilation
environment and search for a similar line? If you find something relevant, let
us know.
