[Buildroot] [PATCHv2 2/2] package/glibc: bump to version 2.29

[Romain Naour]

Changes to build and runtime requirements:

* Python 3.4 or later is required to build the GNU C Library.

* On most architectures, GCC 5 or later is required to build the GNU C
  Library.  (On powerpc64le, GCC 6.2 or later is still required, as
  before.)

While at it, remove the double "glibc-" prefix in the version.
