[toolchain/eglibc] set version string of eglibc version 2.14 to 2.14.1

[toolchain/eglibc] set version string of eglibc version 2.14 to 2.14.1

eglibc version number depends on the branch and on the maintenance release
(i.e. the SVN revision). Changing the revision may change the maintenance
version. This patch correlate the SVN revision to the correct version
number - without this change  eglibc 2.14 provoke build errors when
building the base-files package (example, for 2.14):

$ make package/base-files/compile V=1
   make[1] package/base-files/compile
   make[2] -C package/opkg host-compile
   make[2] -C package/base-files-network compile
   make[2] -C package/base-files compile
