This is a bit clunky, but you could try something like :
gcc -o foobar foobar.c \
-Wl,--dynamic-linker=/path/to/your/lib/ld-uClibc.so \
-Wl,-rpath=/path/to/your/lib \
-Wl,-rpath=/path/to/your/usr/lib
I haven't tried, so I don't know if it really works, but it probably
should. Running your programs inside a chroot is definitely a better
solution.

Thomas
