I don't think there is an uclibc.conf file, but I assume you're talking
about uClibc .config file.

I am not an uClibc expert, but my understanding is that uClibc does not
provide ABI compatibility between versions and configurations.
Therefore, you cannot assume that programs compiled against version
A/configuration A of uClibc will work properly with version
B/configuration B of uClibc.
