This commit adds a target 'eglibc' package. For now, there is no way
to build this package, the next commit will add the integration of
eglibc into the Buildroot toolchain backend.

#

#  1. We have to build out-of-tree, but we can't use the same

#     'symbolic link to configure' used with the gcc packages.

#

#  2. We have to execute the configure script with bash and not sh.
