These functions are very basic stuff in uClibc, so your problem is
most likely not uClibc here.

You have two choices:

 * Use the external toolchain backend, which allows you to use a
   pre-built CodeSourcery or Linaro toolchain for ARM, or build your
   own toolchain with Crosstool-NG, and then use it into Buildroot as
   an external toolchain.

 * Use the Crosstool-NG backend, which will tell Buildroot to use
   Crosstool-NG to build the toolchain.

Both of those solutions will allow you to use the glibc C library.
