Buildroot not designed for stable uClibc

Hello,

I noticed uClibc-0.9.28 asks on the command line for undefined configs when building toolchain with Buildroot, because .config syntax has changed since 0.9.28 version.

For instance, HAS_FPU was renamed to UCLIBC_HAS_FPU, BUILD_UCLIBC_LDSO and DL_FINI_CRT_COMPAT were removed.

Is it not recommended to use latest uClibc stable release in Buildroot ? May I fall into some caveheats ? What benefits can I expect using uClibc snapshots ?

Thank you !

Benjamin
