What exactly are you trying to do; just setting PICO_CLIB to another value won't work at the moment, since the CLIB is bundled with the compiler. Perhaps you have a compiler which bundles multiple clibs, i which case this (setting PICO_CLIB to pick amongst them) will probably be supported in the future, but thus far we have not tested it.

TLDR is that PICO_CLIB is not a config parameter yet
