toolchain/crosstool-NG: add C library config munging
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) Signed-off-by: "Yann E. MORIN" <yann.morin.1998@anciens.enib.fr> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>
