toolchain/crosstool-NG: add C library config munging

Browse Source 
For some C libraries, it can be necessary to push the BR settings
down to the libc configuration file. Prepare the infrastructure.

(Note: it will apply only to uClibc for now, and although eglibc
can also be configured, it is not currently supported)
